Abstract
Colloidally synthesized quantum dots of CsPbBr3 are highly promising for light-emitting applications. Previous reports based on benchtop diffraction conflict as to the crystal structure of CsPbBr3 quantum dots. We present X-ray diffraction and PDF analysis of X-ray total scattering data that indicate that the crystal structure is unequivocally orthorhombic (Pnma).
摘要
通过胶体合成的CsPbBr3量子点在发光应用方面极具潜力。先前基于台式衍射的报告对于CsPbBr3量子点的晶体结构存在冲突。我们展示了对X射线全散射数据的X射线衍射和PDF分析，结果表明其晶体结构明确为正交晶系（Pnma）。
