Abstract
Blue OLEDs are of a particular interest as they are needed in the development of full color display and white lighting. However, blue OLEDs have a very poor efficiency in comparison to green and red OLEDs [1]. In addition, the color of the emitted light is generally not stable due to the apparition of Green Emission Bands (GEB) allowing a broadened electroluminescent spectrum of the OLED S. Liu, R. Wu, J.
