摘　　要：采用流变相法合成了掺杂三价铽离子的对甲基苯甲酸锌发光材料。在紫外灯的照射下,观察比较了对甲基苯甲酸、对甲基苯甲酸锌以及掺杂Tb(Ⅲ)的对甲基苯甲酸锌盐的荧光现象,利用荧光分光光度计测定了三者的激发光谱和发射光谱,并讨论三者的发光特性和机理。结果表明:对甲基苯甲酸作为有机配体可以改善Tb3+离子的发光性能。The method of flowing alterant phase was adopted to synthesize Tb3＋-doped zinc p-toluic acid phosphor in this paper.In the ultraviolet light exposure,observation may tell whether the fluorescence intensity of Tb3＋-doped zinc p-toluic acid,zinc p-toluic acid and p-toluic acid are different or not.By using fluorescent spectrophotometer three compounds’excitation spectrum and emission spectra can be obtained.And the three compounds’properties and the mechanism of light according to the graph are discussed.As a result, the p-toluic acid as an organic ligand can improve the Tb^3＋ ion luminescent properties.
