摘　　要：Blue and white top-emitting organic light-emitting devices OLEDs with cavity effect have been fabricated. TBADN：3%DSAPh and Alq3：DCJTB/TBADN：TBPe/Alq3：C545 were used as emitting materials of microcavity 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 obtained 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.Blue and white top-emitting organic light-emitting devices OLEDs with cavity effect have been fabricated.
