In previous paper, we reported new high performance blue emitting materials, 9,10-bis(3’’,5’’-diphenylbiphenyl-4’-yl)anthracene (TAT) and 4-(1’-(3’,5’-diphenylbiphenyl-4-yl)anthracen-9-yl)-N,N-diphenylaniline (TATa) which have electroluminescence (EL) maximum values of 443nm and 469nm. OLED devices were fabricated and characterized by co-deposited emitters of TAT and TATa with different ratio. The above figure shows EL spectra of the devices according to different ratio. EL maximum wavelength was changed from 443nm to 469nm. |
