摘要:

分别以稀土配合物为发光中心,以PPV、Alq3为空穴输送层和电子输送层制备了结构为ITO/PPV/PVK:PBD:Eu(DBM)3/Alq3/Al的电致发光器件,其中发射层由旋涂法形成,该器件的最大亮度为52cd•m-2,且具有很好的单色性.

关键词: 电致发光, 铕配合物, 旋涂法

Abstract:

 Eu3+ narrow band emitting EL device with PPV, Alq3 as hole and electron transportation layers has been prepared. The emitting layer, which consists of PVK, Eu(DBM)3 and PBD is f0rmed by spin-casting method. A maximum luminance of 52cd•m-2 is achieved from the device.

Key words: Electroluminescence, Europium complex, spin-casting method
