摘要：

The electroluminescent device ITO/Cul/3,6-di(9-carbazolyl)-9-(2-ethylhexyl)carbazole(TCz1)/Ca/Al in which TCz1 for the first time was used as the emitting layer, was fabricated by means of vacuum deposition. The device emits blue light with a peaks at 388 and 406 nm at 4.5V, with high current efficiency values (11.5 cd/A) and external quantum efficiency (1.72%). (C) 2011 Elsevier B.V.
