本文对在３６５ｎｍ波长紫外光激发下均可发出特征荧光的铕、铽邻苯二甲酸固体络合物以机械混合和化学作用两种混合方式，研究了这两系列混合络合物的荧光光谱和红外光谱。结果表明，无论其荧光发射波长还是其发射强度，铕、铽之间均存在相互影响；其中荧光发射峰位的变化较小，而荧光强度变化较大；铕、铽的荧光性能之间既存在相互敏化作用，又存在相互猝灭作用。红外光谱结果表明机械混合和化学作用都使络合物的结构发生了变化
In this paper, the fluorescence spectra of europium and terbium phthalic acid which can emit characteristic fluorescence when excited by ultraviolet light of 365nm wavelength are mixed by both mechanical and chemical methods. IR. The results show that there is interaction between europium and terbium, no matter the fluorescence emission wavelength or its emission intensity. The change of fluorescence emission peak is small but the fluorescence intensity changes greatly. The fluorescence properties of europium and terbium both exist Mutual sensitization, there is mutual quenching effect. Infrared spectroscopy results show that both mechanical mixing and chemical reactions have changed the structure of the complex
