Potassium halides (KX; X = I, Br, or Cl) were incorporated as partial replacements of CsBr in the mechanosynthesis of CsPbBr. This led to partial substitution of both monovalent ions forming mixed Cs K PbBr X perovskites. Longer photoluminescence lifetimes were also observed, possibly linked to the formation of a non-perovskite KPbX passivating layer.
卤化钾（KX；X = I、Br或Cl）在CsPbBr的机械合成中作为CsBr的部分替代物被引入。这导致了一价离子的部分替代，形成了混合的CsK PbBrX钙钛矿。还观察到了更长的光致发光寿命，这可能与非钙钛矿KPbX钝化层的形成有关。
