Abstract

A deep blue phosphorescent organic light-emitting diode was developed using a diphenyldi(4-(9-carbazoly)lphenyl)silane(SiCa) host material and a tris((3,5-difluoro-4-cyanophenyl)pyridine) iridium(FCNIr) dopant material. Triplet bandgap of the SiCa was 3.0 eV, while triplet bandgap of the FCNIr was 2.8 eV. Light-emitting performances of blue devices were investigated by changing doping concentration of the FCNIr and a pure blue emission with a color coordinate of (0.15, 0.19) could be obtained.
