Paper Abstract

White light emission from an Organic light emitting device (OLED) with a microcavity was demonstrated. The structure of the microcavity OLED is Glass/DBR/ITO/TPD/Alq/Al. The microcavity is sandwiched between a distributed Bragg reflector and a metal Al reflective mirror. The ITO and Al were used as the anode and cathode, respectively. The TPD was used as the hole transport layer, and the Alq was used as the light-emitting layer, which has a typical broad bandwidth. A white light emission was achieved due to the multimode emission of the microcavity. The emission peaks of the microcavity were located at 462 nm, 555 nm and 615 nm, respectively.
