Blue and white top-emitting organic light-emitting devices OLEDs with cavity effect have been fabri- cated. TBADN:3%DSAPh and Alq3:DCJTB/TBADN:TBPe/Alq3:C545 were used as emitting materials of micro- cavity OLEDs. On a patterned glass substrate, silver was deposited as re?ective anode, and copper phthalocyanine (CuPc) layer as HIL and 4’-bis[N-(1-Naphthyl)- N-phenyl-amino]biphenyl (NPB) layer as HTL were made. Al/Ag thin films were made as semi-transparent cathode with a transmittance of about 30%. By changing the thickness of indium tin oxide ITO, deep blue with Commission Internationale de L’Eclairage chromaticity coordinates (CIEx,y) of (0.141, 0.049) was obtained on TBADN:3%DSAPh devices, and different color(red, blue and green)was ob- tained on Alq3:DCJTB/TBADN:TBPe/Alq3:C545 devices, full width at half maxima (FWHM) was only 17 nm. The spectral intensity and FWHM of emission in cavity devices have also been studied.
