Cathodoluminescence of MAPbCl Halide Perovskite Single Crystal.

Chloride perovskites are semiconductors with a near-ultraviolet bandgap that are promising for applications in optoelectronics and photonics. One of the most studied representatives of this family is the methylammonium lead chloride MAPbCl (MA = CHNH). Low-temperature luminescence spectroscopy of this material demonstrates a complex emission structure.
