유기발광소자의 적색 발광 특성 향상에 관한 연구

A Study on the Improvement of Red EL characteristics for Organic LED device

In this study the emission characteristics of Sq dye undoped and doped specimen investigated. In Sq 14mol% doped specimen, OXD7 and Alq3 layer interpolated. This effect has been observed and mechanism characteristics have been examined. For OXD7 insert, hole flow the cathode intercept, and then hole accumulated. Because of increasing recombination probability of electron and hole highly pure color maintained. Simultaneously brightness characteristics and emission efficiency could improve.
