Thermally activated sensitization of organics by lanthanide complexes for near-infrared photochemical upconversion

Abstract

A series of solid-state triplet–triplet annihilation upconversion systems have been developed utilizing a penta-nuclear Yb complex as the sensitizer, converting near-infrared light into blue, green and red photons. The endothermic sensitization of organic annihilators by the Yb complex enables an anti-Stokes shift exceeding 1.3 eV.
