We demonstrated a facile method to grow organometal halide perovskite quantum dots in a solid silica matrix. The photoluminescence measurements of the MAPbBr₃ quantum dots and corresponding large particles show a shift from blue to green emission with morphological changes. The nanocrystals impregnated on the silica matrix improve the stability and may be useful as functional materials in all solid state light emitting devices.

的溶液表面处理调制有机铅卤化物钙钛矿量子点用硅胶G集成大的纳米晶体†

我们展示了一种在固体二氧化硅基质中生长有机金属卤化物钙钛矿量子点的简便方法。MAPbBr ₃量子点和相应的大颗粒的光致发光测量结果显示，其形态发生了从蓝光到绿光的转变。浸渍在二氧化硅基质上的纳米晶体提高了稳定性，并且可用作所有固态发光器件中的功能材料。
