White organic light-emitting devices were fabricated by 9,10-bis (2-naphthyl) anthracene (ADN) doped with rubrene. Multilayer organic devices using AND and rubrene as an emitting layer produce white emissions with good chromaticity and current efficiency of 5.93 cd/A at 140 mA/cm². A maximum luminance of 9300 cd/m² is obtained at the driving voltage of 21 V. The Commission Internationale de L’Eclairage coordinates of the white emission are in the white zone (0.32,0.40). This performance can be explained by F?rster energy transfer from the blue-emitting host to the orange-emitting dopant.
