AI Article Synopsis
- The photoluminescence (PL) from CsPbBr nanocubes (NCs) can be significantly enhanced when they are assembled into ordered arrays.
- The quantum yield (QY) of the PL increases with light exposure and decreases when in the dark, which is a repeatable process seen in the arrays.
- The spaces between the NCs in these arrays facilitate changes in surface ligands that influence the PLQY, a phenomenon not observed in isolated NCs.
Article Abstract
A repeatable enhancement of the photoluminescence (PL) from CsPbBr nanocubes (NCs) is promoted by the assembling of NCs. The PL quantum yield (QY) of ordered NC arrays increases with photoirradiation and decreases in the dark. The repeatable enhancement of the PLQY cannot be observed from isolated NCs. The nanospaces between NCs in the ordered arrays allow a reversible change in thermally stimulated desorption and photo-induced adsorption of surface ligands that affect the PLQY.
