Dynamic Control of Photoluminescence for Self‐assembled Nanosheet Films Intercalated with Lanthanide Ions by Using a Photoelectrochemical Reaction

Abstract

Getting turned on: A photoelectrochemical reaction has been used to control the photoluminescence of self-assembled nanosheet films intercalated with Ln3+ ions. Emission (em) occurs under anodic bias (mechanism shown) and not under cathodic bias because of the oxidation and reduction of Ln3+/Lnn+ by holes and electrons by UV light, respectively (see picture, VB=valence band, CB=conduction band), which allows control of the emission on/off response.
