High-Efficiency CsPbBr₃ Light-Emitting Diodes using One-Step Spin-Coating In Situ Dynamic Thermal Crystallization.

ABSTRACT: All-inorganic perovskite materials (such as CsPbBr₃) have received widespread attention because of their better stability than hybrid counterparts, but their poor film morphology and crystalline quality limit their application in perovskite light-emitting devices (PeLEDs). Some previous studies have attempted to improve the morphology and crystalline quality of perovskite films by heating the substrate, but there are still some problems such as inaccurate temperature control, excessive temperature is not conducive to flexible applications, and the mechanism of action is not clear. In this work, we used a one-step spin-coating, low-temperature in situ thermally assisted crystallization process, in which the temperature was accurately monitored using a thermocouple in the range of
