2,4,6-trichlorobenzoic acid terbium complex/calcium carbonate composite fluorescent material and preparation method thereof

The present invention provides a 2,4,6-trichlorobenzoic acid terbium complex/calcium carbonate composite fluorescent material and a preparation method thereof. The preparation method comprises the steps of reacting terbium chloride with 2,4,6-trichlorobenzoic acid and calcium carbonate to prepare the 2,4,6-trichlorobenzoic acid terbium complex composite fluorescent material with calcium carbonateas a matrix. The performance of the 2,4,6-trichlorobenzoic acid terbium complex composite fluorescent material is characterized. The composite fluorescent material provided by the invention is good influorescent performance and long in fluorescent life, the usage of rare earth ions is reduced, and the cost of the rare earth complex fluorescent material is reduced. The preparation method is simplein process and convenient to operate. 本发明提供了2,4,6-三氯苯甲酸铽配合物/碳酸钙复合荧光材料及其制备方法，所述制备方法为利用氯化铽与2,4,6-三氯苯甲酸和碳酸钙反应，制得以碳酸钙为基体的2,4,6-三氯苯甲酸铽配合物复合荧光材料，并对其性能进行表征，本发明提供的复合荧光材料荧光性能好，荧光寿命长，而且节约了稀土离子的用量，降低了稀土配合物荧光材料的成本。本发明的制备方法简单，操作方便。
