摘要
A (PEA)(2)PbI4 (2D) layer deposited on a MAPbI(3) (3D) film undergoes a transformation upon photoirradiation and thermal treatment. The decrease in absorption and emission of the 2D layer during light and heat exposure, which shows migration of the PEA(+) cation within the 3D film, points out the dynamic nature of the 2D/3D interface and intermixing of the two phases.
