    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: Disclosed is an electroluminescent device comprising a cathode and an anode and, located therebetween, a light-emitting layer (LEL) comprising a phosphorescent guest material, a hole- and electron-transporting host material, and an efficiency-enhancing material having an ionization potential lower than that of the host material and a triplet energy level that is lower than that of the phosphorescent guest material by no more than 0.2 eV. Such a device provides useful light emission features.
