摘要： A simple and efficient method of increasing conductivity of the fluorocarbon film is disclosed. By illuminating the fluorocarbon film under ultraviolet light (UV-CFx), the film conductivity can be increased by five orders of magnitude. Devices using such a UV-treated, conductive fluorocarbon film as a buffer layer give much better performance in terms of lower operational voltage and enhanced operational stability. The improved smoothness and lowered hole injection barrier height with UV-CFx are responsible for the enhanced performance of electroluminescent devices.
