✦ Synopsis

The interface between the organic layer and the Indium Tin Oxide (ITO) layer of an organic light-emitting diode (OLED) is crucial to the performance of the device. An ultra-thin Ag 2 O film, used as an anode modification layer, has been employed on ITO surface through the UVozone treatment of Ag films. The insertion of this thin film with higher work function enhances the hole injection in the organic light-emitting diode and improves the performance of the devices effectively. The maximum electroluminescence (EL) efficiency of the device with the Ag 2 O film is 4.95 cd/A, it is about 60% higher than that of the device without it.
