摘要：

A novel transparent conducting oxide, PrTiO3-doped indium oxide (IPTO), is developed via double source reactive electron beam evaporation technology. The film exhibits a high work function of 5.14 eV and its stability is demonstrated in air for two months. The numerical values of optical and electrical properties of IPTO film and the commercial ITO are similar. Two OLEDs were fabricated by employing IPTO and ITO as anode, respectively. For device with IPTO anode, the peak luminance is 85140 cd/m2 and maximum external quantum efficiency is 3.16%, which are 3 times and 1.13 times of the ITO device. It has been demonstrated that the improvements in device performance are achieved for the IPTO-anode OLED. ©, 2015, Chines Academy of Sciences. All right reserved.
