버퍼층으로서 플라즈마 polythiophene이 유기EL소자에 미치는 영향

초록

The purpose of this thesis is to develope buffer materials by the plasma polymerization method. In this article the buffer materials, plasma poly thiophene(PPTh) is used to study the interface of meter/organic in organic light emitting diodes(OLED). The interface of meter/organic materials is the important and critical objectives in development of OLED. The hole transport layer was N,N＇-dipheneyl-N, N＇bis-(3-methypheneyl)-1,1＇dipheneyl-4,4＇-diamine (TPD); the host material of emission layer was 8-tris-hydroxyquinoline aluminium (Alq3). When PPTh was inserted between ITO and TPD, emission effciency increased.
