Plasmon-Enhanced Blue-Light Emission of Stable Perovskite Quantum Dot Membranes.

ABSTRACT: A series of stable and color-tunable MAPbBr_3-xCl_x quantum dot membranes were fabricated via a cost-efficient high-throughput technology. MAPbBr_3-xCl_x quantum dots grown in-situ in polyvinylidene fluoride electrospun nanofibers exhibit extraordinary stability. As polyvinylidene fluoride can prevent the molecular group MA⁺ from aggregating, MAPbBr_3-xCl_x quantum dots are several nanometers and monodisperse in polyvinylidene fluoride fiber. As-prepared MAPbBr_3-xCl_x quantum dot membranes exhibit the variable luminous color by controlling the Cl^- content of MAPbBr_3-xCl_x quantum dots. To improve blue-light emission efficiency, we successfully introduced Ag nanopartic
