The fluorescent dye molecules have gained wide attention for their applications in areas such as imaging and sensor. However, the properties of the fluorescent dyes are limited due to the built-in problems such as the aggregation-caused quenching (ACQ). Herein, a fluorescent dye@MOF was developed by encapsulating fluorescent dye molecules into the channels of metal-organic frameworks (MOFs) to disperse them. This composite material SRB@UiO-66, equipping appreciable stability, was successfully obtained with sulfonyl rhodamine B (SRB) integrated into UiO-66. The composite material overtly accelerated the fluorescence property of SRB due to the limitation of nanometer channels on SRB , while UiO-66 has some fluorescence properties. Besides, SRB@UiO-66 with dual emission centers can be utilized as ratiometric sensors for Fe 3+ detection in aqueous solution owing to their high sensitivity and selectivity. SRB@UiO-66 shows a new possibility to fabricate fluorescent molecular probes for the determination of heavy metal ions .

Rare earth-doped luminescent materials have been widely applied in various fields, both in scientific research and practical applications. Recently, motivated by the demand for advanced smart platforms with multicolor and stimuli-responsiveness properties, the design of a single matrix containing a variety of emitting centers has become a trend in the development of luminescent materials. In this study, the design of a smart platform upon the combination of trivalent bismuth and lanthanides ions (Ln3+) in a LuNbO4 fergusonite-type matrix is reported. Importantly, it is found that such Bi3+/Ln3+ co-activated niobates exhibit multiple stimuli-responsiveness and noteworthy color-tunability. Lastly, we demonstrate the possible application of color-changeable indicators for information readouts via luminescent inks using LuNbO4:Bi3+/Ln3+. This work not only offers guidance for developing color tunable and stimuli-responsive inorganic luminescent materials, but also presents great promise in fields from information security, anticounterfeiting, and optical sensing to smart platforms and beyond.

Fluoroquinolone antibiotics, a class of animal and human useful antibiotics, are widely utilized in numerous fields including biomedical science, animal husbandry, and aquatic finfish farming. Its high demand and wide application have directly or indirectly led to substantial consumption and discharge of antibiotics, affecting not only the environment but also endangering human health through bioaccumulation. Hence, rapid and precise detection of trace antibiotics in water, food, and biological samples is critically important. This research synthesized Tb 3+ /Eu 3+ complexes with dual emission centers, and a fluorescence sensor array was constructed with the fluorescence intensity ratio F 1 /F 2 of the two emission centers as a signal. Different sensitization effect of fluoroquinolone antibiotics towards lanthanide complexes aided in differentiating five fluoroquinolone antibiotics from two others. Additionally, the sensor array can effectively detect fluoroquinolone antibiotics in real samples, suggesting its reliability and practicality of complex sample analysis. The excellent qualitative and quantitative analysis ability of this strategy for fluoroquinolone antibiotics offers a novel perspective for antibiotic residue detection, showcasing a new opportunity for lanthanide complex application in sensor arrays.

Materials exhibiting long-persistent luminescence (LPL) in the visible spectrum hold pivotal importance for anti-counterfeiting and encryption. Nevertheless, conventional LPL materials generally possess a fixed afterglow color. This constraint makes it imperative to develop multimodal luminescent systems featuring spectrally tunable afterglow. Herein, the Er3+/Sm3+ co-doped Ca3Ga4O9 phosphors achieve multicolor photoluminescence (PL), upconversion luminescence (UCL), and color-tunable LPL by responding to multiple excitations modes ranging from ultraviolet (UV) to near-infrared radiation (NIR). Spectral analysis reveals a green-to-orange multicolor afterglow by varying the relative concentrations of Er3+ and Sm3+ ions. To unravel the mechanism of multicolor afterglow, afterglow spectra and thermoluminescence (TL) spectra are systematically employed to probe the trap distribution mediated by Er3+ and Sm3+ co-doping. Finally, their prospective application in optical anti-counterfeiting and information encryption is also systematically investigated based on the color-tunable LPL. This successful integration of multicolor, multimodal luminescence with color-tunable afterglow in a single host provides a novel platform for anti-counterfeiting and encryption, significantly expanding the visual diversity of displayable information.

Broadband near-infrared (NIR) emitting materials have gained considerable attention for their applications in lighting, displays, sensing, bio-imaging, and optical amplification. Recently, numerous excellent broadband NIR emitting materials are developed by introducing Cr 3+ , Bi + , or Ni 2+ ions to various hosts. However, there is a notable absence of reports on ultra-broadband NIR emitters spanning the entire telecommunication window as well as the NIR-I (700–1000 nm) and NIR-II (1000–1700 nm) biological windows activated by vanadium ions. Herein, the study presents, for the first time to the best of the knowledge, ultra-broadband NIR emission ranging from 850 to 1600 nm (peaking at ≈1000 nm) at room temperature in vanadium-doped phosphate glass. Detailed spectra and microscopic structure analysis reveal that two V 3+ -emitting centers predominantly contribute to the ultra-broadband emission, corresponding to 3 T 2 ( 3 F)→ 3 A 2 ( 3 F) spin-allowed and 3 T 2 ( 3 F)→ 1 E( 1 D) spin-forbidden electron transitions of tetrahedrally coordinated V 3+ ions. Notably, the tunability of NIR emission peak is demonstrated by adjusting the local glass structure or the vanadium doping content. Moreover, glass-converted light-emitting diodes (gc-LEDs) are fabricated from vanadium-doped glass, and the potential applications are demonstrated. The work opens new avenues for the design and fabrication of broadband NIR-emitting materials and opto-electronic devices.
