第一个例子的三重态-三重态湮灭为基础的光子上转换（TTA-UC）从绿色光紫外（UV）光敏化卤化铅钙钛矿纳米晶体。从钙钛矿中提取三重态能量的新发射器和具有低三重态能级的UV发射器的组合延长了钙钛矿敏化的上转换UV发射的激发波长。
The first example of triplet-triplet annihilation-based photon upconversion (TTA-UC) from green light to ultraviolet (UV) light sensitized by lead halide perovskite nanocrystals is demonstrated. The combination of a new transmitter that extracts triplet energy from perovskite and a UV emitter with a low triplet energy level lengthens the excitation wavelength of perovskite-sensitized upconverted UV emission.
