A blue, organic, light-emitting diode (OLED) has been made from a new blue emitting material. The structure of the blue device is indium tin oxide (ITO)/CuPc/NPB/JBEM:perylene/Alq/MgAg. Here copper phthalocyanine (CuPc) is used as a buffer layer, N,N'-bis-(1-naphthyl)-N,N'-diphenyl-1,1'-biphenyl-4,4'-diamine (NPB) as the hole transporting layer, 9,10-bis(3'5'-diaryl)phenyl anthracene (JBEM) as the blue emitting host, perylene as the blue dopant, Tris(8-guinolinolato) aluminium complex (Alq) as the electron transporting material, and M-Ag alloy as the cathode. The blue device has a maximum luminance of 7526 cd/m(2), and the luminance at a cut-rent density of 20 mA/cm(2) is 408 cd/m(2). It has a maximum efficiency of 1.45 lm/W., Commission Internationale de l'Eclairage (CIE) co-ordinates x = 0.14, y = 0.21, and a half-life of 1035 h at initial luminance of 100 cd/m(2). It shows a better stability than the blue device from distyrylarylene derivatives as the blue emitting host, and also perylene as the dopant with the same structure.
