Ultrastable, Highly Luminescent Organic–Inorganic Perovskite–Polymer Composite Films

Abstract

A simple yet general swelling-deswelling microencapsulation strategy has been developed to achieve well dispersed and intimately passivated crystalline organic-inorganic perovskites nanoparticles within polymer matrixes and results in a series of highly luminescent CH₃ NH₃ PbBr₃ (MAPbBr₃ )-polymer composite films with unprecedented water and thermal stabilities and superior color purity.
