Abstract Mn-doped CsPbCl3 perovskite nanocrystals (PeNCs) glass was prepared by melt-quenching and in-situ crystallization. Under the protection of robust glass, PeNCs exhibit excellent moisture resistance and thermal stability. Due to the combination effect of thermal quenching and energy transfer of exciton-to-Mn2+, the emission intensity of Mn shows an abnormal temperature-dependence with the temperature increasing from 80 to 300 K, which can be explored further in the application of temperature sensor. Interestingly, by matching with ultraviolet chips, all-inorganic blue-red emitting conversion device consisting of PeNCs glasses were prepared for light-emitting diodes (LEDs), which can meet the light requirements of plant growth. The cultivation results indicated that growth of cabbages using PeNCs plant cultivation LEDs were greater than those cultivated using commercial w-LEDs. Therefore, Mn-doped CsPbCl3 PeNCs can be used as a new-generation of solid fluorescent materials in the field of indoor plant cultivation LEDs.
