以金属铊为原料，用硝酸溶解-碘化钾沉淀-真空升华的方法制备了高纯碘化铊，并且制备出多种球形碘化铊复合卤化物。碘化铊既可以单独用作绿光材料，也可以作为添加剂与其它金属卤化物复合得到复合金属卤化物发光材料，满足不同的使用要求。文章用图表介绍了碘化铊用作金属卤化物灯发光材料时的发光特性。
High pure thallium iodide was made through the process of dissolving thallium in nitric acid, precipitating thallium ion by potassium iodide then subliming thallium iodide in vacuum. A series of spherical composite halides containing thallium iodide was made. Thallium iodide is used as green luminous material. It is also used as addition agent contained in composite halides of thallium iodide for different forms of application. Luminous characters of thallium iodide used as luminous material in metal halide lamps are presented.
