Abstract
Abstract Mn‐doped CsPbCl 3 perovskite nanocrystal (PeNC) glass was prepared by melt quenching and in situ crystallization. Under the protection of robust glass, PeNCs exhibit excellent moisture resistance and thermal stability. The combination effect of thermal quenching and energy transfer of exciton to Mn 2+ enables its promising applications in the field of temperature sensor. Interestingly, by matching with ultraviolet chips, all‐inorganic blue‐red emitting conversion device consisting of PeNC glass was prepared for light‐emitting diodes (LEDs), which can meet the light requirements of plant growth. The cultivation results indicated that the growth of cabbages using PeNC plant cultivation LEDs was greater than those cultivated using commercial w‐LEDs (white light‐emitting diodes). Therefore, Mn‐doped CsPbCl 3 PeNCs can be used as a new generation of solid fluorescent materials in the field of indoor plant cultivation LEDs.
