Distinctive excitonic recombination in solution-processed layered organic–inorganic hybrid two-dimensional perovskites†
Abstract
Two-dimensional (2D) perovskites are under extensive focus due to their natural multiple quantum well structures and intense excitonic luminescence. Here we provide comprehensive photoluminescence studies on solution-processed (C6H5C2H4NH3)2PbI4 crystals. The synthesized crystals exhibit three single excitonic emissions with different luminescent nature of 0D-like excitons, 2D localized excitons, and self-trapped excitons, respectively.
