N2 - CsPbBr3 perovskite quantum dots (QDs) demonstrate tremendous utility value in the photoelectric field due to their high fluorescence intensity. However, their engineering application is limited by their poor stability. Herein, a general strategy for the preparation of CsPbBr3 QDs homogeneously encapsulated in poly(vinylidene difluoride) (PVDF) by electrospinning is provided. The fabricated CsPbBr3 QDs demonstrate uniform and well dispersed in PVDF, and a high quantum yield of fluorescence. The temperature dependence of photoluminescence (PL) spectra of the CsPbBr3@PVDF film shows great linear relationship between full width at half maxima and temperature. By coating silicone resin (SR) on the electrospinning film, the thermal stability, water stability and mechanical strength of the CsPbBr3 QDs are significant improved. Meanwhile, their PL spectra still keep great temperature dependence. Outstanding optical performances and stability of the CsPbBr3@PVDF-SR film make it can be used as a sensor to monitor the temperature of bearing rotating elements.
