Metal halide perovskites present a vast potential for the development of cutting-edge optoelectronic devices. However, their vulnerability to environmental factors, especially humidity, leads widely acknowledged stability challenges. On other hand, such high sensitivity water in atmosphere is an opportunity humidity sensing applications. In this study, we synthesize lead perovskite CsPbBr3 nanocrystals within CaCO3 templates with porous structure (CsPbBr3@CaCO3) and investigate mechanisms underlying fluorescence response changes relative humidity. The reversible transformation CsPb2Br5 removal surface defects, which results increase photoluminescence intensity, thereby enabling determination ambient levels. Moreover, investigated mechanism degradation driven by CO2 humid environments transformations. As proof concept, developed fluorescence-based sensor based on CsPbBr3@CaCO3 rapid recovery times, maintaining performance across multiple cycles.
