Abstract

We demonstrate a new strategy for the in situ formation of highly luminescent CH₃NH₃PbBr₃ perovskite planar film via the reaction between PbBr₂ and methylamine gas. The obtained CH₃NH₃PbBr₃ perovskite planar film exhibited similar quantum confinement to solution chemistry synthesized colloidal CH₃NH₃PbBr₃ quantum dots. Such quantum confinement was realized by a PbO_x/Pb(OH)₂ framework, which is a by-product formed in situ from the reaction of PbBr₂ and methylamine gas under ambient conditions.
