Highly Luminescent Lead Bromide Perovskite Nanoparticles Synthesized with Porous Alumina Media

Abstract

Abstract Nanocrystalline lead bromide perovskite was synthesized by rapid self-organization on a mesoporous aluminum oxide film. With UV excitation, the film exhibited an intense green emission with a narrow bandwidth. The photoluminescence intensity is optimized for the conditions of synthesis and the kind of metal oxide.
