摘要：

以正硅酸乙酯作为硅源,异丙醇铝作为铝源,采用化学修饰的方法将其共价键嫁接到3, 5-二羟基苯甲酸配体(DHBA)上,得到了前驱体Si DHBA Al,然后将前驱体和第2配体1,10 邻菲啉同时与稀土铽离子配位,从而得到了基于Si Al复合基质的稀土杂化发光材料Tb(Si DHBA Al)₃phen.通过红外光谱、紫外可见漫反射、X射线衍射、扫描电镜对材料的结构和形貌进行了表征,同时还研究了稀土杂化材料的荧光性质.结果表明杂化材料发射出铽离子的特征发射光谱,是一种优良的发光材料.

Abstract：

In this paper,3,5-dihydroxybenzoic acid(DHBA) was covalently bonded to Si-O network and Al-O network via chemical modification forming the precursor Si-DHBA-Al.Then the precursor Si-DHBA-Al and the ligand 1,10-phenthanroline(phen) were coordinated to terbium ion to obtain a rare earth hybrid luminescent material Tb(Si-DHBA-Al)₃ phen.The hybrid material was characterized by FTIR spectra,UV-vision diffuse reflection absorption spectra,X-ray diffraction and SEM microscopy.In addition,the luminescent property of hybrid material was investigated,and the results show that the terbium hybrid material exhibit characteristic emssion of terbium ion.
