Zhang Zhilin Jiang Xueyin Xu Shaohong(Department of Materials Science, Shanghai University Jiading Campus, Shanghai 201800)Nagatomo T Omoto O(Shibaura Institute of Technology, Shibaura 3-9-14 Minato-Ku, Tokyo 108. Japan)  
Rubrene is doped into the hole transport layer of an organic thin film electroluminescent (OTFEL) device with a double-layered structure. It is found that the dopant has profound influences on the EL characteristics. It changes the region of light emission and thus the EL spectrum, increases the luminescence efficiency by more than 50% and improves the device stability by 10 times. The effect of the dopant on the energy relation of the materials discussed.
