| Abstract(in English) | We has been synthesized bis(1,4-bis(5-phenyloxazol-2-yl)phenyl)iridium(picolate) [(POB)_2Ir (pic)] as a red emitting materials and evaluated in the organic light emitting diodes (OLED). The layer of tris(8-quinolinolato) aluminum [Alq_3] doped with [(POB)_2Ir (pic) as emitters has been demonstrated. The structure of the device is indium-tin-oxide (ITO)/N,N'-bis-(1-naphthl)-diphenyl-1,1'-biphenyl-4,4'-diamine (NPB, 40nm) / Zn(HPB)_2 (40nm)/ Alq_3 : (POB)_2Ir (pic) (30nm) / LiF / Al. We varied the doped rate of (POB)_2Ir (pic). The doped rate is 0.4%, 0.6%, 0.8 and 1.2%, respectively. When the doped rate of the Alq_3: Ir(POB)_2(pic) was 0.6%, white emission is achieved. The Commission Internationale de l'Eclairage (CIE) coordinates of the white emission are (0.316, 0.331) at an applied voltage of 10.75V. |
