New green dopant of TCBzC substituted carbazole units was investigated in solution process WOLED device. 4-(10-(3',5'-diphenyl-biphenyl-4-yl)anthracen-9-yl)-N,N-diphenyl-aniline (TATa) and 4-(dicyanomethylene4)-2-t-butyl-6(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) were used for the blue host and red dopant. A structure of the device was fabricated as ITO / PEDOT (40 nm) / PVK (14nm) / EML: TATa + TCBzC: 3.0wt% + DCJTB: 0.08wt% (50 nm) / TPBi (20 nm) / LiF (1 nm) / Al. As a result, TCBzC device of 1.44 cd/A was obtained. CIE value of TCBzC device was (0.26, 0.41). |
