Abstract

Hybrid materials consisting of semiconductor nanocrystals and metal–organic frameworks (MOFs) were prepared for the first time to achieve photon upconversion based on triplet–triplet annihilation (TTA-UC) in the solid-state, which allowed TTA-UC with large anti-Stokes shifts in the visible and near-infrared regions.
