采用短链c4nh9nh3x （X= Cl, Br， I）化合物作为独特的封盖剂，可以在室温下在露天条件下合成高质量的CH3NH3PbX3 （X= Cl, Br， I）钙钛矿量子点，该量子点具有较高的光致发光量子产率和在440 ~ 660 nm范围内可调谐的发射特性。此外，C4H9NH3Br还可以通过自旋涂覆CH3NH3Br、C4H9NH3Br和PbBr2的N， N-二甲基甲酰胺溶液，改善CH3NH3PbBr3薄膜的形貌，使薄膜致密致密，提高其光学性能。
Employing the short-chain C4H9NH3X (X= Cl, Br, I) compound as the unique capping agent, highly quality CH3NH3PbX3 (X= Cl, Br, I) perovskite quantum dots can be synthesized at room temperature in the open air, which possess high photoluminescence quantum yields and tunable emission in the range of 440-660 nm. Besides, C4H9NH3Br can also improve the morphology of CH3NH3PbBr3 thin films by spin-coating the N, N-dimerthylformamide solution of CH3NH3Br, C4H9NH3Br and PbBr2, making the thin film dense and compact, and improving its optical properties.
