The Fabrication and Analysis of the White Organic Electroluminescent Devices by varying the Doping Concentrations of Rubrene and the Thickness of NPB layer

Rubrene의 도핑량과 NPB층의 두께변화에 따른 백색 유기전계발광소자 제작 및 분석

We have been fabricated the white organic electroluminescent devices using vacuum evaporation method. The structure of the white OELD is Glass/1T0/NPB/DPVBi/AI $q_{3:}$ Ru bren e/B CP/Alq $q_3$/Al. We have got the white emission with two-wavelength that is mixing blue emission in DPVBi layer and orange emission in Al $q_{3:}$Rubrene layer by varying tile doping concentrations of Rubrene and the thickness of NPB layer.yer.
