Abstract
The white organic light emitting diode(OLED) with two-wavelength was fabricated using the DPVBi of blue emitting material and a series of orange colar fluorescent dye(Rubrene) by vaccum evaporation processes. The basic structure of OLED was ITO/TPD$(225{\AA})$/DPVBi/Rubrene/BCP$(210{\AA})/Alq_3(225{\AA})/Al(1000{\AA})$. We analyzed the fabricated device through the changes of the DPVBi and Rubrene layer's thickness. We obtained the white OLED with the CIE coordinate of the device was (0.29, 0.33) and luminescence of $1000cd/m^2$ at applied voltage of 15V when 4he thickness of DPVBi layer was 210${\AA}$ and the thickness of Rubrene layer was 180${\AA}$.
