Abstract

Organic electroluminescence (EL) devices were fabricated using a bis(2-methyl-8-quinolinato) aluminum hydroxide complex [Al(Mq)2OH] as the light-emitting material. The device exhibits bright blue EL at a peak wavelength of 485 nm. A maximum luminance of about 14,000 cd/m2 can be achieved at a driving current density of 480 mA/cm2. The efficiency of the device is about 4.6 cd/A. Possible mechanisms of EL blue shift of Al(Mq)2OH with respect to Alq3 are discussed.
