Featured with a tunable excitation/emission wavelength and excellent physicochemical stability, inorganic fluorescent materials are widely used in the fields of anti-counterfeiting. Here, we design multi-stimuli-responsive dynamic fluorescence phosphorescence anti-counterfeiting material by introducing Eu3+ ions NaGdGeO4: Bi3+ to tailor trap structure. The photoluminescence (PL), long persistent luminescence (LPL), photo-stimulated (PSL) colors Bi3+, can be switched varying excitation modes (ultraviolet, near infrared, X-ray light). Especially, LPL PSL vary increasing decay stimulation times. In addition, ensures specificity compared ultraviolet excitation. This rapidly-changing-color offers possibility sophisticated applications future.

Metal halide double perovskites with splendid optical features have been considerably investigated for optoelectronic applications. Herein, a series of Mn2+-doped Cs2NaLuCl6 perovskite crystals were prepared. Via adopting the density functional theory calculation, effect Mn2+ doping on electronic structure compound was discussed. It found that crystal can emit intense blue light from host self-trapped exciton (STE) emission. Excited by 320 nm, STE and emissions simultaneously observed in resulting crystals. Owing to efficient energy transfer Mn2+, polychromatic luminescence final products. Moreover, taking advantage various responses emission intensities temperature, thermometric characteristics investigated, their maximum relative sensitivity is 0.99% K-1, which hardly impacted content. Furthermore, prepared exhibit good X-ray radioluminescence properties, low detection limitation 0.99 μGyair s-1. Additionally, utilizing designed crystal, flexible imaging high resolution 20 lp mm-1 be operated high-temperature environment realized. These results indicated are suitable thermometry imaging.
