A white organic light emitting diode (OLED) was fabricated in which a blue light emitting host DPVBi was doped with a red dye DCJTB. The device structure was ITO/CuPc/NPB/DPVBi:DCJTB/Alq/LiF/Al, where CuPc is copper phthalocyanine, NPB is N,N'-bis-(1-naphthyl)-N,N'-diphenyl-1,1'-biphenyl-4,4'-diamine, DPVBi is 4,4'-bis(2,2-diphenylvinyl)-1,1'-biphenyl, DCJTB is 4-(dicyanomethylene)-2-t-butyl-6(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyr an, and Alq is tris(8-quinolinolato) aluminium. White light emission was realized in an OLED with 0.08% DCJTB doping concentration by weight. The fabricated white OLED showed a little shift from blue to red with the increase of injection current, e.g. the CIE coordinates from (0.26, 0.32) at 4 mA/cm 2 current density to (0.24, 0.30) at 400 mA/cm 2 current density. The maximum luminance reaches 7822cd/m 2 , and the maximum luminous efficiency is 1.75lm/W (2.45cd/A) at 20 mA/cm 2 .
