This communication describes a strategy to synthesize stable deep blue FAPbBr quantum dots (QDs) by constructing a matrix structure. Amorphous Ni-based metal halide matrices can stabilize QDs from both chemical and physical factors, and Ni doping can further enhance their structural stability due to lattice shrinking. Such deep blue QD films exhibit stable X-ray diffraction patterns and photoluminescence even after 245 days of storage.
本通讯描述了一种通过构建矩阵结构来合成稳定的深蓝色FAPbBr量子点（QDs）的策略。非晶态镍基金属卤化物矩阵可以从化学和物理因素两方面稳定量子点，并且镍掺杂由于晶格收缩可以进一步增强其结构稳定性。即使在储存245天后，这种深蓝色量子点薄膜仍表现出稳定的X射线衍射图案和光致发光特性。
