Abstract
The electroluminescent device ITO/CuI/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 4.5 V, with high current efficiency values (11.5 cd/A) and external quantum efficiency (1.72%).
► The blue OLED based on non-doped film of TCz1 was fabricated. ► Electroluminescence spectrum is similar to photoluminescence spectrum. ► Device exhibit high current efficiency of 11.5 cd/A and EQE of 1.72%.
