Recent experimental findings, rapidly accumulating over the past few years, has revealed that in electronic excited states of metal nanoclusters (MNCs) composed noble atoms (e.g., Cu, Ag, or Au), triplet are generated with remarkably high efficiency, exerting a pivotal influence photophysical properties MNCs, notably their photoluminescence characteristics. As result, MNCs increasingly recognized as promising luminescent nanomaterials exhibit room-temperature phosphorescence and thermally activated delayed fluorescence. Furthermore, significance triplet-state-mediated energy transfer charge intermolecular processes is gaining increasing recognition, particularly applications photosensitizers for singlet oxygen organic molecular triplets. This Perspective focuses on recent advances understanding formation photophysics MNCs. Additionally, brief overview provided series studies exploring use sensitizers photon upconversion via triplet-triplet annihilation, future prospects this emerging application discussed.
