摘　　要：本文以六水合氯化铽(TbCl_(3)·6H_(2)O)作为原料、以2,4-二氯苯甲酸作为唯一配体,用碳酸钙作为碱和内核、乙二醇作为溶剂,在无水条件下,通过稀土铽离子与配体进行配位反应制备发绿光的新型铽配合物复合荧光材料。通过荧光分析、紫外分析、红外分析、热重分析、XRD、ICP等表征实验,对制备的新型铽配合物复合荧光材料的性能进行研究。从实验结果可知,随着试验温度的改变,从紫外、红外谱图以及XRD结果中,可以得出各个温度制备的复合材料的铽配合物都附着在载体上的结论;荧光复合材料的发射强度在制备温度为90℃时能达到1257310cps;由荧光寿命可知,在100℃制备的荧光复合材料的寿命最长能达到1.00662ms。In this paper,a new type of terbium complex fluorescent material was prepared by the coordination reaction of rare earth terbium ions with terbium chloride(TbCl_(3)·6H_(2)O)in anhydrous condition,using 2,4-dichlorobenzoic acid as the only ligand,calcium carbonate as base and core,and glycol as solvent.Fluorescence analysis,ultraviolet analysis,infrared analysis,thermogravimetric analysis,XRD,ICP and other characterization experiments were carried out to study the properties of the new terbium complex composite.The results showed that the terbium complex of the composite prepared at different temperatures attached to the carrier.The fluorescence emission intensity of the composite material can be achieved respectively when the preparation temperature is 90℃1257310 CPS;By fluorescence lifetime,the preparation of fluorescence composite materials in the 100℃life expectancy can reach 1.00662 ms.
