inorganic perovskite composites for light emitting diodes

In recent years, there has been significant interest in all-inorganic perovskite materials due to their remarkable qualities, which include extended stability, adjustable light absorption spectra, suitable energy bandgap, extensive carrier diffusion length, and elevated photoluminescence quantum yield (plqy). these extraordinary optical characteristics and stability make them highly promising contenders for optoelectronic devices. this paper explores inorganic perovskite composites and their applications in the development of light-emitting diodes (leds). firstly, the fundamental concepts of all-inorganic peleds have been explicated. subsequently, the introduction of inorganic perovskite composites peleds has been presented. particularly, we have comprehensively provide a review the synthesis methods employed for all-inorganic nanocrystals (nc) , including hot-injection, ultrasonication, room-temperature and vapor deposition techniques. furthermore, we have outlined various strategies aimed at enhancing the efficiency of all-inorganic composite peleds.
