This study discovered that a transparent BaF 2 -B 2 O 3 glass system without rare-earth ions prepared under CO-reducing atmosphere exhibited orange-red self-luminescence under near-UV light, generating broadband luminescence from 550∼850 nm centered at 650 nm under broadband light excitation at about 397 nm. Based on the results of spectra, electron spin resonance, Raman, and X-ray photoelectron spectroscopy, it is proposed that the luminescence phenomenon is due to the s→p transition of B 2+ generated inside the glass under the reducing atmosphere. This new luminescent glass has the potential to be an orange-red luminescent material excited by a light-emitting diode.

The development of phase change materials (PCMs)-based energy storage devices for both thermal and light energy has the potential to greatly enhance solar energy use efficiency, which is important in addressing the worldwide energy problem. Due to the environmentally friendly, good thermal and chemical stability, easy degradation, and good mechanical strength of ethyl cellulose, it was used to fabricate the shape-stabilized composite phase change material (ss-CPCM) with polyethylene glycol. The ss-CPCMs have a high latent enthalpy (174.33 J/g), high form stability, excellent thermal regulation abilities for both thermal energy storage and thermal insulation, and great cycle thermal performance. After adding long afterglow luminescence particles, the self-luminous ss-CPCMs were obtained. They can absorb and store visible and ultraviolet light, as well as emit green light in the dark for an extended period of time. The excellent properties of the self-luminous ss-CPCMs promise them great potential in applications, such as energy-saving, emergency lighting, furniture, smart building, and smart highway.

NIR phosphors based on commercial LED pumping are gained great concerns. However, blue excitation and lack of broadband NIR phosphors are still obstacles. Herein, NIR-II emitting ZnGa 2 O 4 : Fe 3+ , Ni 2+ with autologous defects are designed. Self-PL is associated with intrinsic defects including [GaO 6 ], antisite defects ( G a Z n · $Ga_{Zn}^ \cdot $ ) and oxygen defects ( O i ). Based on efficient energy transfer, ZGO: Fe 3+ , Ni 2+ exhibits broadband NIR-II emission. To improve PL efficiency of Fe 3+ , an oxygen defects repairing engineering via anionic F − -substitution artifice is executed, resulting in high PL quantum efficiency of ≈64.6% and splendid thermal stability (≈75.5%@423K) for ZGOF: Fe 3+ , Ni 2+ . The reduction in local site symmetry after F-substitution splits energy states of Fe 3+ in purely octahedral crystal field also helps to relief the Laporte selection rule and widens excitation/PL spectra with high efficiency. A NIR-II phosphor-converted LED (pc-LED) by combination of ZGOF: Fe 3+ , Ni 2+ and a n UV LED chip via remote ʻcappingʼ packaging strategy with high radiant power is fabricated and its versatile applications in night vision, non-destructive detection, food analysis and optical pressure sensing are demonstrated. This study paves a feasible way to realize high-quality NIR phosphor and its corresponding device for wide applications.

Most of near-infrared (NIR) persistent luminescence (PersL) materials can only be activated by ultra violet-visible light illumination or X-ray irradiation, which hinders their advanced biomedical applications. Herein, NaYTi 2 O 6 : Cr, with a typical double-metal perovskite structure, is developed with ∼758 nm emission after being excited by 700 nm light within the NIR bio-imaging window. This NIR-to-NIR PersL property can be repeatedly charged by 700 nm NIR illumination in situ and in vivo . The anti-cite disorder of Na + -Y 3+ pair and relatively low bandgap of NaYTi 2 O 6 matrix are the vital factors of this property. NaYTi 2 O 6 : Cr has great potential to be applied as a functional ceramic coating in designing self-luminescent medical Ti-implants, so that it can be imaged in vivo by using NIR PersL imaging rather than conducting risky X-ray fluoroscopy imaging. This conceptual work not only provides a NIR-to-NIR PersL biomaterial but also is significant in designing visible medical implants.

Triple negative cancer (TNBC) is characterized as an aggressive phenotype lacking a specific therapeutic target. To date, self-illuminating photodynamic therapy (PDT) based on chemiluminescence resonance energy transfer (CRET) has emerged as a potential alternative for TNBC treatment by generating singlet oxygen ( 1 O 2 ), overcoming limitations in light penetration. However, this self-illuminating strategy heavily relies on endogenous hydrogen peroxide (H 2 O 2 ) and oxygen (O 2 ) within the tumor microenvironment (TME), resulting in inefficient therapeutic performance. In this study, we designed CLT@DPD nanoparticles capable of self-illumination via CRET and TME regulation through self-supplying H 2 O 2 and O 2 . This nanoparticle was constructed by encapsulating luminol-tetreaphenylporphyrin conjugate (LT) and nanoscale CaO 2 with DSPE-PEG 2000 and dioleoylphosphatidylcholine (DOPC). A good accumulation at tumor site was achieved due to enhanced permeability and retention (EPR) effect after intravenous injection of CLT@DP. Responsive to the high H 2 O 2 levels and acidic aqueous conditions of TME, LT can be oxidized to produce 1 O 2 via CRET, and the CaO 2 can be decomposed to supply H 2 O 2 and O 2 . Additionally, the presence of DOPC helps to enhance the permeability of the micelle shell under the oxidation of 1 O 2 , thereby accelerating the release of H 2 O 2 and O 2 . Our proposed nanoparticles exhibit excellent performance in eradicating in situ tumor cells and inhibiting metastasis by simultaneously enhancing self-luminous PDT and alleviating oxygen depletion in TME.

Photodynamic therapy is a tumor treatment strategy. However, most of the photodynamic therapies rely on laser irradiation triggering, which limits their application in deep tissues. This study designed a self-luminescent nano system, hybrid protein oxygen nanocarrier coated graphene quantum dots (GQDs@HPOC) and mesoporous silica nanoparticles coated Luminol (L@MSNs), which self-assembled into GQDs@HPOC/L@MSNs without laser irradiation. The system utilized the weak acidic environment of tumors to trigger the release of Luminol and the chemiluminescence was catalyzed by HPOC. Next CRET occurred between Luminol and GQDs , producing 1 O 2 , which could generate photodynamic damage to cervical cancer cells without the need for external laser irradiation. The system achieved the peak uptake in primary cervical cancer cells in 3 h, and had good biosafety before self-assembly. The system could significantly kill cells at a concentration of 16 μg/ml. The system will be further applied in in vivo experiments to investigate its therapeutic ability, providing a new strategy for the clinical treatment of cervical cancer.

Magnesium oxychloride (MOC) based materials have attracted much concern because of the superior mechanical properties and environmental friendliness, however, the widespread application is limited by the poor water-resistance and the tedious function. Thus it is worthwhile devoting much effort to overcome the defects. Here, taking sandpaper as template and with the modification of fluorinated HPDMS and luminescent powder, an effective method is proposed to produce MOC based composite with superhydrophobicity, self-luminescence and reusability. The samples can keep superhydrophobic (SHP) after enduring mechanical and chemical treatments, and even the crushed sample is still superhydrophobic. Meanwhile, SHP modification is helpful for overcoming the poor water-resistance, because the main phases are protected by the hydrophobic layer. After excitation, the composite materials can emit green light, which will gradually decay with time. The superhydrophobicity makes the material endure to be used for buildings with self-cleaning and deicing ability. Moreover, the powders ground from waste samples exhibit superhydrophobicity, implying the potential recyclability of this material, which can be applied to SHP luminous coating for house decoration and traffic signs in darkness, and directional water transport as well.

The design and synthesis of high-efficiency electrochemiluminescence (ECL) emitters hold great promise for a wide range of analytical applications. In this study, we developed a rapid and straightforward strategy to fabricate a self-luminous Cd-based metal–organic framework (Cd-MOF) using individual aggregation-induced emission ligands, specifically 1,1,2,2-tetrakis(4-(pyridin-4-yl)phenyl)ethane (TPPE), within a few seconds. The rigid and directionally enriched metal node of Cd, along with the organic ligands, is formed within the Cd-MOF via coordination, effectively constraining the intramolecular free motions of TPPE and suppressing nonradiative relaxation. Additionally, the unique porous structure combined with the catalytic activity resulting from the incorporation of Cd2+, endow the Cd-MOF with 90-fold ECL enhancement compared to individual TPPE as more chromophores are electro-excited and more coreactants are catalyzed to produce luminescence. The as-made Cd-MOF amplifies the ECL performance by integrating ECL emitters and coreactant accelerators into a single entity, simplifying the sensing process. Leveraging the excellent ECL performance, we constructed a sensitive ECL sensor for hydroquinone based on competitive reactions, with a wide linear range from 200 nM to 1 mM and a satisfying detection limit as low as 80 nM.

The development of flexible self-luminous reversible thermochromic passive energy-saving composites (TPCMs) is self-challenge due to the defects of easy leakage, non-visibility, solid phase rigidity, and weak light absorption . So, the emerging TPCMs were cleverly constructed using wood aerogel as support skeleton and different mass ratios of natural latex/long afterglow components as flexible and self-luminescent matrix based on optimal binary fatty alcohol eutectic (C 14 C 20 ). Among them, C 14 C 20 R-TEW-1R and C 14 C 20 G-TEW-0.35 P stand out with suitable phase transition temperatures (28.8 °C and 29.7 °C), high latent heat values (100.5 J g −1 and 119.4 J g −1 ), and low supercooling (0.7 °C and 0 °C). Induced by phase change, they change from rigid to flexible, from red/green to milky white, and can absorb light to achieve self-luminescence in the dark (orange red and blue-green) and enhanced photothermal efficiency. Beyond the traditional thermal/light stability and excellent anti-leakage performance, TPCMs realizes the combination of temperature sensitivity/control and self-luminous, providing broad application prospects in home automation, passive energy-saving in buildings, luminescent response switches, and other fields.

Photodynamic therapy (PDT) is a minimally invasive and local light-activated treatment for annihilating tumor tissues. However, it is often limited by the tissue penetration depth of common external light sources. To address this issue, we herein report a self-illuminating ZIF-90 MOF-based composite photosensitive system prepared using a combined one-pot self-assembly and post-synthetic modification (PSM) methodology. The obtained PME@Zn/Fe-ZIF-90-Lum consists of the Fe(II)-doped and luminol-decorated MOF host as well as the protoporphyrin IX dimethyl ester (PME) guest. Under the given conditions, the light, which is generated from the Fe(II)-catalysed luminol oxidation by endogenous H2O2, can in situ activate the encapsulated photosensitizer PME to produce reactive oxygen species (ROS) via a chemiluminescence resonance energy transfer (CRET) process. In the absence of an external light source, antitumor PDT is successfully realized and high phototoxicity is fully evidenced by in vitro and in vivo experiments.

The penetration ability of visible light (<2 mm) and near-infrared (NIR) light (∼1 cm) remarkably impairs the therapeutic efficacy and clinical applications of photodynamic therapy (PDT). To address the limitation of light penetration depth, a novel self-luminescent bacterium, teLuc.FP-EcN, has been engineered through transfection of a fusion expression plasmid containing the luciferase gene teLuc and bright red fluorescent protein mScarlet-I into Escherichia coli Nissle 1917 (EcN). The engineered teLuc.FP-EcN can specifically target and colonize tumors without significant toxicity to the host. Acting as a continuous internal light source, teLuc.FP-EcN can activate the photosensitizer chlorin e6 (Ce6) to generate reactive oxygen species (ROS) and then effectively destroy tumor tissue from the inside. As a result, a significant reduction in tumor proliferation and extension of the overall survival in mouse tumor models has been observed. Furthermore, teLuc.FP-EcN-boosted PDT amplified its therapeutic effect by activating antitumor immune response, including the conversion of M2 macrophages into pro-inflammatory M1 macrophages, as well as an increase in the proportion of CD3+ T cells and a decrease in T-cell exhaustion. In conclusion, teLuc.FP-EcN can be used as an implantable light source for tumor phototherapy, which simultaneously possesses ROS generation and immune regulation.

Locally induced photodynamic therapy (PDT) with internally generated light could offer opportunities for the efficient treatment of deep tissue tumors and bacteria hidden in places where external light cannot reach. To achieve this, luminol acrylamide was synthesized and used to prepare nanospheres that were loaded with a polyurethane photosensitizer and the enzyme horseradish peroxidase. With H 2 O 2 the nanoparticles were self-illuminating and showed good antibacterial abilities and also anticancer effects via a PDT mechanism indicating efficient self-luminous functionality. The self-luminating nanospheres could potentially be used in sterilization and for cancer depression.
