ABSTRACT:
In order to improve the performance of polymer light-emitting devices, driving voltages, current efficiency, luminance and power efficiency of different cathode metals such as Ca/Al, CsF/Al, LiF/Al and LiF/Ca/Ag were compared. The results show that cathode metals CsF/Al contain the highest current efficiency, maximum luminance and power efficiency. Therefore, we can choose the CsF/Al to be the cathode for improving the performance of polymer light-emitting devices.
