Abstract

In this paper, we was fabricated and analyzed a blue organic electroluminescent devices with the organic dye, such as 1,1,4,4-Tetraphenyl-1,3-butadi-ene(TPB). The device was made by simultaneously co-depositing two materials. The device structure was composed of the ITO glass, TPD, Alq$_3$doped TPB, and aluminum(A1) electrode. Carrier injection from the two electrodes was significant]y observed and the blue light in EL spectrum, with an emission maximum at 462nm, was triggered at a driving voltage of 11V.
