Near-Infrared Photoluminescence in Mo-Doped Single Crystals of CuAlS 2
Near-infrared photoluminescence (PL) spectra were measured at 6 K in single crystals of CuAlS 2 doped with different amounts of Mo. A fine-structure PL emission was observed around 1,600 nm (0.775 eV) in both lightly and heavily doped crystals. The emission was tentatively assigned to the ligand-fie...
