Abstract

The construction of high-efficient white organic light-emitting devices (WOLED) with phosphorescent/fluorescent dual-emitting architecture was described. Fluorescent material, 9,10-bis-(β-naphthyl)-anthrene (DNA) was used as a blue-light source to overcome the color-stability limitations found for all-phosphor-doped WOLEDs and phosphorescent platinum(II) complexes to achieve balanced white light. Two-component phosphorescent/fluorescent WOLEDs were constructed by combining the orange or green-yellow light emission from the complexes wit the blue-light emission from DNA. The organic layers were deposited by thermal evaporation onto a cleaned glass substrate precoated with transparent, conductive indium tin oxide under high vacuum. The electroluminescence spectra, brightness, CRI, and CIE of OLEDs were measured with a Photo Research Inc. PR650 luminance meter.
