    摘要: Disclosed is an electroluminescent device comprising a cathode and an anode; and, located therebetween, a light-emitting layer (LEL) comprising a phosphorescent green-light-emitting material and a host material for the light-emitting material, and in a layer adjacent to the LEL on the anode side, an exciton-blocking layer containing a compound having a hole mobility of at least 1×10−3 cm2V−1s−1 and a triplet energy exceeding that of the green-light-emitting material of the LEL. Such a device provides useful light emission.

    摘要: An OLED device comprises a cathode, an anode, and has therebetween a light-emitting layer containing a phosphorescent emitter that emits yellow, orange or red light; a tertiary arylamine compound as a first host material, and a gallium complex with only nitrogen bidentate ligands as a second host material. Desirably, the phosphorescent emitter is an iridium complex.
