This letter presents a deep blue organic light emitting diode which was fabricated by using 9,10-di(2-naphthyl)anthracene as a dopant and 4,4'-N,N'-dicarbazole-biphenyl as a host. The Commission Internationale de l'Eclairage coordinates of (0.1516,0.0836) were achieved in the cell, which is very close to the National Television Standards Committee standard of (0.14,0.08). Meanwhile, maximum luminance over 6500 cd/cm(2) and maximum current efficiency of 3.5 cd/A were also obtained. (C) 2007 Elsevier B.V. All rights reserved.
