铕高分子配合物红色薄膜电致发光特性
Red Electroluminesence Europium Polymer Complex
摘要
合成了三价铕的高分子配合物, 主链高分子采用丙烯酸和甲基丙烯酸甲酯的共聚物, 引入邻菲咯啉(phen)和二苯甲酰基甲烷(DBM)作为第二配体。 研制了结构为ITO/PVK/Eu3+-polymer/Al的器件, 起亮电压为8.5 V, 在16 V下看到了明显的红色发光。 研究了它的光致发光和电致发光性质,发现电致发光和光致发光的光谱有明显不同的特征,对其可能的机理作了探讨。
Abstract
The Eu3+-containing polymer ternary complex was synthesized. And it was used as the emitting layer of the organic electroluminesence (OEL) device successfully. The red light of Eu3+ from the electrominesence (EL) device was seen at 16 V. A considerable difference between the EL and photoluminesence (PL) spectra was observed. It was noticed that two spectra were very different. In PL spectrum the main peak was at 618 nm. But for the OEL spectrum, there are two peaks at 595 nm and 657 nm. The probable mechanism was discussed.
