Efficient Electroluminescence from Tris(4-methyl-8-quinolinolato)aluminum(III)
A green-light-emitting aluminum complex, tris(4-methyl-8-quinolinolato)Al (III) (Almq<SUB>3</SUB>), was synthesized and used as an emitter material in organic electroluminescent (EL) devices. The device structure of glass substrate / indium-tin oxide / tetraphenyldiamine derivative / Almq<SUB>3</SUB> / Mg:Ag was employed. The EL device exhibited efficient green light originating from Almq<SUB>3</SUB> with a maximum luminance of 26000 cd/m<SUP>2</SUP> at 14 volt. The maximum external quantum efficiency was 2.5% photons / electron.
