Japanese Research Group Develops New Rare Metal-free Phosphorescent OLED Device

A Japanese research group led by Chihaya Adachi and Kenichi Goushi, professors at the Center for Organic Photonics and Electronics Research (OPERA) of Kyushu University, has developed a high-efficiency phosphorescent OLED device without using any rare metal. It has an external quantum efficiency of higher than 5%, as one of the highest in the world for phosphorescent OLED devices that do not contain any rare metal.   Because phosphorescent materials can realize an internal quantum efficiency of 100%, they are popular in being using in high-efficiency OL...
