University of northern Dezhou developed a 42% efficient white phosphorescent OLED

North Dezhou (North Texas) University developed a white phosphor OLED 42% high, the work is the result of cooperation and the University of Dezhou development, the Department of energy to develop the efficiency of 50% OLED, the results from the goal of some. The device uses a single doped material that can be tuned by varying the concentration of the dopant. Conventional white OLED uses a wide variety of doped materials, each of which emits a color and is then mixed into a variety of colors. This is only a single material, is a major breakthrough.
