Paper Abstract

A blue organic light-emitting diode has been made by anthracene derivative. The structure of the blue device is ITO/m-MTDATA/NPB/doped anthracene/Alq3/Mg:Aag, where m-MTDATA, NPB and undoped Alq3 were used for hole injection layer, hole transporting layer, and electron transporting layer, and electron tranporting layer, respectively. Three different of blue fluorescent dyes, inclduign BCzVBi, perylene, and TBPe, were introduced into anthracene as dopants for obtaining a highly luminescent blue emission. Evidence shows that the BCzVBi-doped device behaves the superior L-J and J-V characteristics due to the higher fluorescence and the formation of conducting path for carrrier transport. The emission mechanism was strongly suggestd to be due to energy transfer process from anthracene host to BCzVBi dopant and achieving a highly luminescent blue-light.
