合成了一类新型的以苯甲酰水杨酸(benzoylsalicylicacid,BSA)为第一配体,邻菲罗啉(1,10 phenanthroline,phen)为第二配体的稀土配合物Eu(BSA)3phen,将导电高分子材料PVK引入到配合物中,制成了结构为ITO/PVK∶RE配合物/LiF/Al的电致发光器件。通过测量电致发光和光致发光光谱,发现PVK∶RE配合物混合体系存在着能量传递,并对Eu(BSA)3phen与PVK共混体系的光致发光和电致发光机制进行了分析。同时比较了几种不同PVK掺杂浓度对于器件性能的影响。
A new class of rare earth complexes Eu (BSA) 3phen with benzoylsalicylic acid (BSA) as the first ligand and phenanthroline (phen) as the second ligand was synthesized. , The conductive polymer material PVK was introduced into the complex to make an electroluminescent device with the structure of ITO / PVK: RE complex / LiF / Al. By measuring electroluminescence and photoluminescence spectrum, it was found that PVK: RE complexes have energy transfer, and the mechanism of photoluminescence and electroluminescence of Eu (BSA) 3phen and PVK blends were analyzed. The effect of several different PVK doping concentrations on device performance was also compared.
