Photoluminescence Excitation Spectroscopy of Defect‐Related States in MAPbI 3 Perovskite Single Crystals

The MAPbI 3 halide perovskite single crystals are studied at 5 K temperature using the photoluminescence excitation spectroscopy. Two noninteracting types of states are determined: bound excitons and defect‐related states. Excitation of the crystal with light energy below the bound exciton resonance...
