摘要：
The indium-zinc-tin-oxide (IZTO) target, which consisted of 70 at.% In2O3- 15 at.% ZnO- 15 at.% SnO2, was manufactured to replace indium-tin-oxide (ITO). The flexible IZTO (FIZTO) transparent electrodes were deposited on polyimide (PI) films at temperatures ranging from room temperature to 300 degrees C. The mechanical, optical and electrical properties of the FIZTO films and the flexible polymer light emitting diodes (FPLEDs) were characterized. Amorphous FIZTO prepared at 50 degrees C showed the best performance. The optimized FPLEDs exhibited 31% and 9% enhanced maximum brightness and luminance efficiency, respectively, as compared to PLEDs with an ITO glass. In addition, the FPLEDs worked normally in the stretching and twisting state at 3.2% and 58 degrees, respectively.
