Abstract

The indium-zinc-tin-oxide (IZTO) target, which consisted of 70 at.% In₂O_3⁻ 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 °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 °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°, respectively.
