The versatility of emission modes and colors in flexible films is essential for broadening their potential applications. This study presents the development of a multi-mode luminescent flexible film by integrating ZnS:Cu and LiNbO3:Pr3+ powders into a polydimethylsiloxane (PDMS) matrix. The ZnS:Cu and LiNbO3:Pr3+ powders are uniformly distributed in the PDMS matrix. The effect of the LiNbO3:Pr3+ content on the photoluminescence (PL), electroluminescence (EL), mechanoluminescence (ML), thermoluminescence (TL), and photostimulated luminescence (PSL) properties of the films has been investigated. The PL colors of the LiNbO3:Pr3+/ZnS:Cu/PDMS flexible films due to the distinct intrinsic emissions of ZnS:Cu and LiNbO3:Pr3+ can be changed by altering the excitation wavelength. An appropriate content of the LiNbO3:Pr3+ powder introduces PSL into the flexible films, while the films demonstrate excellent EL and ML performance, along with multicolored TL emissions, including red and green. This research offers a novel approach to enhancing flexible electronic displays, EL devices, and optical anti-counterfeiting technologies.

Since different quenching mechanisms can endow carbon dots (CDs) with diverse responsive manners, multi-mode sensing can in principle be achieved by a single carbon-dot-based sensor. In this work, green emissive CDs were prepared by simple hydrothermal pyrolysis of phenolphthalein and ethylenediamine at 180 °C for 5 h, with a quantum yield of 17%. The as-prepared CDs can be selectively quenched by Hg2+ due to their specific binding affinity causing photo-induced electron transfer (PET). Due to the inner filter effect (IFE), the CDs also showed intensive fluorescent response to lemon yellow dye. Moreover, the CDs responded to Fe2+ or H2O2 selectively in the presence of H2O2 or Fe2+ owing to oxidative quenching (OQ) by hydroxyl radicals resulting from the Fenton reaction. Via the diverse responsive manners of PET, IFE and OQ, multi-mode sensing for Hg2+, lemon yellow and Fe2+, H2O2 was thus achieved by a single green emissive carbon-dot-based sensor. Accordingly, the linear ranges for the selective detection of Hg2+, lemon yellow, Fe2+ and H2O2 were found to be 0.0–500.0, 0.0–20.0, 0.0–90.0 and 0.0–50.0 μM, with the limits of detection as low as 5.8, 0.5, 1.2 and 1.1 μM, respectively.

In recent years, the proliferation of counterfeit products has led to increased concerns about anti-counterfeiting technology, with traditional single-mode fluorescence methods proving insufficient due to their susceptibility to replication. The new copper-based halide materials have shown great potential in the field of multi-mode anti-counterfeiting due to their unique structure, excellent luminescence performance, and high defect tolerance. In this work, near-infrared emission of Cs 3 Cu 2 I 5 was achieved for the first time through Bi doping. By exploiting the dual emission center characteristics of the resulting Cs 3 Cu 2 I 5 :Bi, we demonstrated its excitation wavelength-dependent emission. It was then mixed with cyclohexane to prepare an advanced fluorescent anti-counterfeiting coating for screen printing, enabling high-precision pattern printing onto various substrates. The resulting anti-counterfeiting patterns exhibit excellent weather resistance, remaining virtually unchanged after 60 days at room temperature. This study lays the foundation for expanding the emission range of Cs 3 Cu 2 I 5 and adjusting multi band emission, and confirms its potential application in the field of multi-mode anti-counterfeiting.

Carbon dots (CDs) nanozymes open a new horizon for fabricating multi-mode analysis systems, but their practical applications are still limited by complicated synthesis strategy and single-function nature. Herein, a new type of iron and nitrogen co-doped carbon dots nanozyme was developed through simple pyrolyzing the solid mixture of ferrous bis-glycinate and ethylenediamine dihydrochloride. The Fe,N-CDs exhibit good optical properties that can emit obvious blue fluorescence and possess excellent peroxidase-like activity that can catalyze H 2 O 2 to generate reactive oxygen species. Based on the fluorescence and peroxidase-like activity of the Fe,N-CDs, a multi-mode detection platform for DA was constructed effectively, including naked eye colorimetric, UV–Vis ratiometric absorption, fluorescence quenching, and scanometric. The limit of detection can reach 10 nM, and the calibration curve was linear up to 30 μM. The multi-mode sensing system was successfully applied for the accurate determination of DA in various actual samples with a satisfactory recovery of 89.0–118.0 %.

Color is an excellent carrier of information between organisms. Photonic elastomers that convert abstract mechanical information into intuitive color information have shown great potential in various application fields. However, angular correlation of structural colors and monotonous color conversion mode affect the accuracy of material information reading and the applicability in diverse application scenarios. Here, inspired by a kind of bright blue spider- Poecilotheria metallica , a new wrinkled photonic elastomer structure is reported. Through wrinkling stretchable 1D photonic crystals (1DPCs), photonic elastomers with both one-directional and omni-directional angle-independent brilliant structural colors are realized. It is worth noting that with the hybrid 1DPC and polydimethylsiloxane substrate support, the wrinkled photonic structure and structural color remain stable after 1000 strain cycles, and mechanochromic sensitivity can reach 3.25 nm/%, indicating strong structural stability and sensitive deformation performance under stress. More importantly, by comprehensively manipulating micro-wrinkle structure and lattice spacing of the photonic films, the structural color can achieve delayed discoloration and invisible-visible reversible switching performance only through a single strain direction. The proposed wrinkled photonic elastomers have a broad application value in the fields of visual strain sensing, wearable devices, and information encryption. Furthermore, it provides a new strategy for color regulation of photonic materials.

The performance and functionality of luminescent materials should be continuously developed to meet the demands of high-level information safety. In this work, a theoretical strategy for multi-mode luminescent color self-evolution in one structure was proposed by hierarchically utilizing the energy transfer processes from traps to luminescent centers. The strategy was further employed for experimental design, and an efficient luminescent structure of CaAl2O4:Eu2+,Mn2+,Er3+,Nd3+ with multi-mode luminescent color self-evolution behaviors was developed. The anticounterfeiting device based on CaAl2O4:Eu2+,Mn2+,Er3+,Nd3+ herein possessed extremely high security level with attractive performance. In addition, the CaAl2O4:Eu2+,Mn2+,Er3+,Nd3+ was confirmed to have energy storage and controllable release activities, based on which high-value encryption devices with dynamic information display were developed.

The fact that both phases are liquids makes it simple to implement counter-current chromatography (CCC), which involves alternating elution modes and phase roles during the separation process. Using two distinct multiple dual-mode (MDM) elution techniques for chiral separation, the team demonstrated a superior separation effect in a prior study. When selecting a chiral selector with high enantiomer recognition capability is difficult, the separation efficiency of the CCC column can be enhanced through multiple cycles. This approach facilitates the preparation of enantiomers that are challenging to isolate under classical CCC conditions. A straightforward mathematical model was created in this study to forecast the number of cycles and the mode conversion time needed for the separation process after the modified MDM method was further examined theoretically. After modeling molecules, the theoretical model was confirmed, and the outcomes generally agreed with the calculations from the theoretical model. This offers substantial support for the modified MDM method's real-world implementation in chiral separation.

Traditional organic light-emitting materials hinder their anti-counterfeiting application in solid state due to their aggregation-caused quenching effect. A facile and straightforward method was reported to introduce AIE molecules into microspheres and manipulate different reaction parameters to prepare AIE microspheres with different morphologies. In this strategy, fluorescent microspheres with spherical, apple-shaped, and hemoglobin-like types were synthesized. Driven by the photocyclization and oxidation of tetraphenylethene, microspheres can be used as an aqueous fluorescence ink with erasable properties. The fluorescent patterns printed by microsphere ink on paper can be irreversibly erased by prolonged exposure to ultraviolet light (365 nm, 60 mw/cm2). Moreover, the multi-morphology microspheres can be further arranged for multiple-information encryption and anti-counterfeiting of barcodes and two-dimensional codes, in which double validation was carried out through fluorescence spectroscopy and laser confocal microscopy. This approach provides a new method for more reliable anti-counterfeiting and information encryption.

A multimode sensing and imaging platform based on surface modification strategy of Ru(bpy) 3 2+ doped SiO 2 nanoparticles (RuSiO 2 NPs) was constructed for versatile detection of glutathione (GSH). RuSiO 2 NPs as the luminophore models had outstanding fluorescence (FL) and electrochemiluminescence (ECL) signals. Furthermore, its FL signal could be captured by electrophoresis analyzer, and the ECL signal could be imaged with mobile phone to achieve visualization. So, a unique and convenient multi-mode sensing and imaging platform could be developed based on RuSiO 2 NPs. SiO 2 NPs could realize enrichment of Ru(bpy) 3 2+ based on the nanoconfined effect to achieve signal amplification, and its surface was rich with abundant hydroxyl functional groups, which offered a channel for surface modification. Sulfhydryl modification on the RuSiO 2 NPs was realized by using silane coupling agent, and KMnO 4 was used to in situ generate MnO 2 shell on the surface of RuSiO 2 NPs for quenching its ECL, FL, and colorimetric (CL) signals based on resonance energy transfer (RET). Target GSH could reduce MnO 2 shell to realize recovery of all signals, thus achieving the label-free multimode detection of GSH. Therefore, this work developed a multimode sensing and imaging platform without signal labels or layer-by-layer assembly of electrodes, which had the advantages of simple steps, low cost, and high detection accuracy, showing important application potential in the field of bioanalysis.

Mechanoluminescence materials that emit light under mechanical stimulation have attracted widespread attention in sensing, anticounterfeiting, and imaging applications. In this study, a series of Sr1–xBixZnSO (0.001 ≤ x ≤ 0.1) samples was synthesized by the method of high temperature solid-state reaction. It is worth noting that the distortion degree of the SrO3S3 octahedron was increased with increasing Bi3+ concentration, and the color manipulated Sr1–xBixZnSO which can emit different photoluminescence (blue to dark blue and finally red) and mechanoluminescence (orange to red) colors is obtained. Moreover, the deep traps can stably store and provide electronic supplements in shallow traps released under mechanical stimulation. Therefore, devices made of SrZnSO:Bi3+ phosphor and polydimethylsiloxane (PDMS) can be used as thermo-mechano-opto three-mode anticounterfeiting. The ML intensity is linear to the external load and can be utilized for stress sensing or imaging.

This study explored the multi-mode upconversion luminescence in YbVO 4 : Er 3+ under a 980 nm laser. The optimal doping concentration of Er 3+ ions in YbVO 4 : Er 3+ is 0.02. The phosphor exhibits green (527 nm, 2 H 11/2 → 4 I 15/2 and 553 nm, 4 S 3/2 → 4 I 15/2 ), red (654 nm, 4 F 9/2 → 4 I 15/2 ) and near-infrared emissions (803 nm, 4 I 9/2 → 4 I 15/2 ). A multi-mode temperature sensor of YbVO 4 : Er 3+ was developed, featuring three temperature sensing modes based on the luminescent intensity ratio (LIR) of 2 H 11/2 / 4 S 3/2 thermally coupled level, as well as the LIR of 2 H 11/2 / 4 F 9/2 and 4 S 3/2 / 4 I 9/2 non-thermally coupled levels. Corresponding maximum relative sensitivities were determined to be 1.21 % K −1 at 298 K, 0.93 % K −1 at 298 K, and 0.33 % K −1 at 473 K, respectively. The phosphor demonstrates notable temperature sensitivity, highlighting its potential in optical temperature sensing. This study introduces an innovative platform for crafting multi-mode self-reference optical temperature sensors, presenting substantial advancements in the field.

Machine learning and data-driven methods have attracted a significant amount of attention for the acceleration of the design of molecules and materials. In this study, a material design protocol based on multimode modeling that combines literature modeling, numerical data collection, textual descriptor design, genetic modeling, experimental validation, first-principles calculation, and theoretical efficiency calculation is proposed, with a case study on designing compatible complex solvent molecules for a halide perovskite film, which is notorious for optoelectronic deactivation under hostile conditions, especially in water. In the multimode modeling design process, the textual descriptors play the central role and store rich literature scientific knowledge, which starts from the construction of a high-dimension literature model based on scientific articles and is realized by a genetic algorithm for materials predictions. The prediction is substantiated by follow-up experiments and first-principles calculations, leading to the successful identification of effective molecular combinations delivering an unprecedented large aqueous photocurrent (increasing by 3 orders of magnitude compared with that of CH3NH3PbI3) and remarkable aqueous stability (improving from 36% to 89% after immersion in water) under the hostile condition. This study provides a practical route via multimode modeling for accelerating the design of molecule-modified and solution-processed materials in a real scenario.
