英文摘要	Color tunable microcavity organic light-emitting diodes (OLEDs) with structure of distributed Bragg reflectors (DBR)/indium-tin-oxide (ITO)/N,N'-di(naphthalene-1-yl)-N,N'-diphenyl-benzidine (NPB)/tris(8-hydroxyquinoline) aluminum (Alq(3))/LiF/Al were fabricated. Orange red and green light emissions with full width at half maximum (FWHM) of less than 20 nm were obtained through simply changing the thickness of NPB layer. Furthermore, due to the effective modification of the spontaneous emission within microcavity, the brightness and electroluminescent (EL) efficiency of the microcavity OLEDs were significantly enhanced. The maximum brightness and current efficiency, respectively, reached 31000 cd/m(2) at a current density of 480.0 mA/cm(2) and 8.3 cd/A at a current density of 110.0 mA/cm(2) for green devices, and 9700 cd/m(2) at a current density of 180.0 mA/cm(2) and 6.6 cd/A at a current density of 36.4 mA/cm(2) for red devices, which are over 1.5 times higher than those of noncavity OLEDs.
