Researchers from RUDN University in Russia have synthesized new OLED emitter compounds. These compounds seem to be phosphorescent emitters, based on copper and silver atoms.
The researchers say that the compound platform they created can lead to efficient and cost-effective OLED emitters, and also offer a special molecular geometry that can enable freedom-of-design for developers.
Copper-doped OLED emitters is not a new idea - this has been researched by RIKEN scientists back in 2011, and by USC researchers earlier this year. TADF-developer CYNORA also started out with an aim to develop copper OLED emitters.
