英文摘要	We demonstrate high efficiency red organic light-emitting diodes (OLEDs) based on a planar microcavity comprised of a dielectric mirror and a metal Mirror. The microcavity devices emitted red light at a peak wavelength of 610 nm with a full width at half maximum (FWHM) of 25 nm in the forward direction, and an enhancement of about 1.3 factor in electroluminescent (EL) efficiency has been experimentally achieved with respect to the conventional noncavity devices. For microcavity devices with the structure of distributed Bragg reflectors (DBR)/indium-tin-oxide(ITO)/V2O5/N,N'-di(naphthalene-1-yl)-N,N'-diphenyl-benzidine(NPB)/4-(dicy-anome-thylene)-2-t-butyl-6(1,1,7,7-tetrame-thyljulolidyl-9-enyl)-4H-pyran(DCJTB):tris(8-hydroxyquinoline) aluminium (Alq(3))/Alq(3)/LiF/Al, the maximum brightness arrived at 37000 cd/m(2) at a current density of 460.0 mA/cm(2), and the current efficiency and power efficiency reach 13.7 cd/A at a current density of 0.23 mA/cm(2) and 13.3 lm/W respectively.
