We report the development of highly efficient and stable C‐545T doped green fluorescent Alq inverted bottom‐emission OLED (IBOLED) which achieved a maximum efficiency of 22.2 cd/A and 12.4 lm/W with an projected t 1/2 of 30,000 h with L 0 = 100 cd/m 2 . The DSA‐Ph doped MADN sky blue fluorescent IBOLED device had a maximum efficiency of 12.7 cd/A and 7.6 lm/W. At a brightness level of 100 cd/m 2 , these green and blue IBOLED devices require drive current densities only as low as 0.5 and 0.9 mA/cm 2 , respectively.
