Incorporation of potassium halides in the mechanosynthesis of inorganic perovskites: feasibility and limitations of ion-replacement and trap passivation

Potassium halides (KX; X = I, Br, or Cl) were incorporated as partial replacements of CsBr in the mechanosynthesis of CsPbBr(3). This led to partial substitution of both monovalent ions forming mixed Cs(1−x)K(x)PbBr(3−y)X(y) perovskites. Longer photoluminescence lifetimes were also observed, possibl...

description Potassium halides (KX; X = I, Br, or Cl) were incorporated as partial replacements of CsBr in the mechanosynthesis of CsPbBr(3). This led to partial substitution of both monovalent ions forming mixed Cs(1−x)K(x)PbBr(3−y)X(y) perovskites. Longer photoluminescence lifetimes were also observed, possibly linked to the formation of a non-perovskite KPb(2)X(5) passivating layer.
