The potential of three-dimensional (3D) metal-halide perovskites to sensitize organic triplets is unveiled. Nanocrystals of surface-modified inorganic cesium lead halide perovskites (CsPbX, X = Br/I) are found to work as efficient triplet sensitizers for photon upconversion based on triplet-triplet annihilation (TTA-UC) at low excitation intensity.
三维（3D）金属卤化物钙钛矿敏化有机三线态的潜力被揭示。研究发现，表面改性的无机铯铅卤化物钙钛矿（CsPbX，X = Br/I）纳米晶体在低激发强度下可作为基于三线态-三线态湮灭（TTA-UC）的光子上转换的高效三线态敏化剂。
