영문 초록

Recently, the phosphorescent organic light-emitting devices (OLEDs) have been extensively studied for their high internal quantum efficiency. In this study, we synthesised several phosphorescent metal complexes, and certified their composition using NMR. We also investigated the characteristics of the phosphorescent OLEDs with the green emitting phosphor, Ir(ppy)_{3}. The devices with a structure of indium-tin-oxide(ITO)/N,N diphenyl-N,N -(3-methylphenyI}-1,1 -biphenyl-4,4 -diamine (TPD)/metal complex doped in host materials/2,9-dimethyl-4,7-diphenyl-l,10-phenanthroline(BCP)/tris (8-hydroxyquinolinato) Aluminum(Alq_{3})/Li:Al/Al was fabricated, and its electrical and optical characteristics were studied. By changing the doping concentration of tris(2-phenylpyridine)iridium (Ir(ppy)_{3}), we fabricated several devices and investigated their characteristics.
