摘　　要：合成了一种新的β-二酮,1,5-二苯乙烯基乙酰丙酮(dsacac)并将其作为第一配体,1,10-邻菲罗啉(Phen)作为第二配体合成了一种新型的铕三元配合物Eu(dsacac)3phen。对配合物进行了元素分析、核磁共振、红外光谱、紫外吸收光谱、光致发光光谱以及热重分析。结果表明:配合物具有较好的热稳定性,起始分解温度为303℃。配合物中的有机配体dsacac和phen能够有效地的把吸收的能量传递给中心Eu3+离子,强烈敏化Eu3+发光,Eu3+发光的最强发射波长为615 nm,半峰宽为9.6 nm。材料的色纯度为0.9866,是一种高效的红色发光材料。A new Europium（ Ⅲ ） ternary complex Eu （dsacac） 3phen, using a novel β-diketone ： 1, 5-styry- lacetylacetone （dsacac） as the first ligand and 1, 10- phenantronline （phen） as the second ligand, was synthesized. Elemental analysis, ^1H-NMR, IR and UVVis spectrum analysis of the new complex were carried out. Meanwhile, the photoluminescence and thermal properties were characterized, which indicated that thenew complex had good thermal stability with decom- posed temperature 303 ℃, and an effective energytransfer from two ligands to center Eu^3 ＋ ions occured in the ternary complex. The maximum emitting wavelength of Eu（dsacac）3phen was 615 nm, FWHM was 9.6 nm and its color purity was 0. 9866, which indicate that this novel complex is an excellent red-emitting material.
