Complete self-recovery of photoluminescence of photodegraded cesium lead bromide quantum dots

Research output: Contribution to journalArticle

Abstract

CsPbBr3 quantum dots were packed in a cell and irradiated at 468 nm. The sample color changed to black, attributed to the formation of surface defects by photoinduced desorption of surface ligands. The color and photoluminescence properties completely recovered during subsequent dark storage. This can be explained by readsorption of the surface ligands.
