摘要

我们开发了一系列固态三重-三重湮灭上转换系统，利用五核镱复合物作为敏化剂，将近红外光转换成蓝、绿和红光子。镱络合物对有机湮灭体的内热敏化使反斯托克斯位移超过 1.3 eV。

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

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.
