“…In some of indium metal–organic compounds, the ligands alone doesn't show any photoluminescent property meaning that rather the ligand-to-metal charge transfer is responsible for the observed photoluminescence. 38 In this study, the emission band of 530, and also the calculated decay times fall in the region of similar works on indium-based complexes. 35,37,42–44 The observed luminescence of this compound is most likely due to ligand-to-metal charge transfers (LMCT) or metal-centered transitions, as the decay times are in the microsecond range.…”
