Abstract
A highly efficient and stable sky blue organic light-emitting device doped with a sky blue dopant BUBD-1 has been fabricated, achieving an electroluminescence efficiency of 13.2cd∕A and 6.1lm∕W at 20mA∕cm2 and 6.7V, with Commission Internationale del’Eclairage coordinates of (0.16, 0.30) and a half-decay lifetime of 1815h at an initial brightness of 2640cd∕m2. This performance is one of the best blue devices ever reported without using hole blocking layer or any p or n dopant in hole or electron transport layer.Keywords
