Abstract

This research focuses on the improvement of internal light out-coupling of organic light emitting diodes (OLED) by incorporating a silica network structure in the device. These structures were fabricated by a self-assembly technique based on the deliquescence of cesium chloride (CsCl) salt. The self-assembled CsCl structure was used as a mask to pattern network structures on silica glass substrate by reactive ion etching (RIE). The light emitting performance of the OLEDs patterned with silica network was investigated. The maximum improvement of luminance efficiency of the silica network patterned OLEDs reaches about 125% compared with a conventional OLED.
