White organic electroluminescence is one approach to achieve full-color flat panel display. A white organic light emitting diode(OLED) with the emitting layer consisting of blue emitting material DPVBi doped with red dye DCJTB is reported. According to the photoluminescence of DPVBi doped by DCJTB with different mass fractions,the OLEDs are demonstrated with the structure of ITO/CuPc/NPB/DPVBi∶DCJTB%/Alq_3/LiF/Al. White light emission can be produced when the mass fractions of DCJTB is 0.0008%. Although the white emission can be produced when the mass fractions of DCJTB is 0.0008%. Although the shite device shows a little increase in relative intensity of blue emission with increasing applied voltage, the consistent results of photoluminescence and electroluminescence indicate that the white light emission mainly originates from energy transfer from DPVBi to DCJTB. For the white light device with CIE coordinates x=0.25, y=0.32, the maximum luminance, the luminance under current density of 20 mA/cm2 and the maximum luminous efficiency are 7822 cd/m2, 489 cd/m2 and 1.75 lm/W, respectively.
