摘要：

A gellated organic light upconversion layer comprising tetraphenylporphryrin sensitizers and diphenylanthracene emitters is attached to a green-emitting high-brightness tandem-OLED to generate deep-blue light. The upconversion efficiency is enhanced by incorporating a longpass filter between the upconverter and the OLED as well as a shortpass filter on the outside of the upconverter.
