Abstract

Visible-to-UV photon upconversion based on triplet-triplet annihilation (TTA-UC) sensitized by lead halide perovskite nanocrystals is demonstrated for the first time. The surface modification of nanocrystals with energy transmitter ligands plays a key role in the effective triplet sensitization, resulting in high TTA-UC efficiency over 4%. This work proves the promising potential of perovskite nanocrystals as a versatile, next-generation triplet sensitizer.
