The structure of NPB(N, N’-bis(1-naphthyl)-N, N’-diphenyl-1, 1’-biphenyl-4, 4’-diamine)blue light-emitting device: ITO/NPB/BCP /Alq3/Mg:Ag was optimized by using Alq3 as additional functional layer due to its hole blocking ability and high fluorescent efficiency. Performance measurement of devices demonstrated that the brightness of the optimized device is about twice higher than that of the un-optimized one. Electroluminescent spectra measurement results show that the light emission of optimized device originates from NPB and Alq3 acts the role of assistant layer of light emission.
