Inorganic Perovskite Composites for Light Emitting Diodes en 10.61186/jcc.5.2.7 en 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 hotinjection, ultrasonication, room-temperature and vapor deposition techniques. Furthermore, we have outlined various strategies aimed at enhancing the efficiency of all-inorganic composite PeLEDs. 140 152 Vahid Keshavarz Department of Materials Engineering, Imam Khomeini International University, Qazvin Iran vahid.keshavarz24@gmail.com Raheleh Zarei Faculty of Chemistry, Kharazmi University, Tehran Iran zarei.rahele@yahoo.com Shima Nasibi Department of Materials Science and Engineering, School of Engineering, Shiraz University, Shiraz Iran shima.nasibi@gmail.com Mehdi Mohabatkhah Department of Engineering, Maku Branch, Islamic Azad University, Azerbaijan Iran mehdimohabatkhah@gmail.com Inorganic perovskite Composite perovskite materials Light emitting diodes LED stability Article7.pdf [1] C.M.
