Lead-free double perovskites (DPs) with excellent moisture, light, and heat stability have been explored as alternatives to toxic lead halide perovskite (APbX3) (A for monovalent cation and X for Cl, Br, or I). However, the bandgaps of the current DPs are generally larger and either indirect or direct forbidden, which leads to weak visible light absorption and limitation for photovoltaic and ... Web使用SiO2可使PL发射强度增加181.5%。此外，与纯Cs2AgInCl6相比，Cs2AgInCl6/ SiO2具有更好的抗氧化和抗离子性损伤的能力。SiO2参与了Cs2AgInCl6晶体的生长，但不改变晶体内部的晶包结构，也不改变晶体的本征的发光机制。变温PL证明白光发射主要来源于STEs。
