Abstract

A red emitting microcavity device with a multiple layer of Glass/DBR/Ag/NPB/DCM:Alq₃/ Alq₃/LiF/Al was fabricated. Comparing with device of Glass/ITO/NPB/DCM: Alq₃/ Alq₃/LiF/Al, the spectrum of the microcavity device was narrowed from 67nm to 27nm and the peak intensity was increased by a factor of 2.5, while the current density was one eighth of that of non-cavity device at the same bias voltage. By inserting an Ag layer between ITO and NPB the current intensity was sharply enhanced about three times and because of weak cavity effects the spectrum changed largely.
