| 摘 要： | 稀土有机配合物发光材料中稀土含量大,制备成本高,价格昂贵.尝试借用无机材料的发光机制,在邻苯二甲酸锶基质中掺杂Eu3+制备邻苯二甲酸锶铕,实现低浓度稀土发光,大幅度减少了稀土离子Eu3+的用量,且产物的荧光强度明显高于纯粹的稀土有机配合物邻苯二甲酸铕.此外,就邻苯二甲酸锶铕的制备条件,包括反应温度、pH值和锶铕配比对产物荧光强度的影响进行了简要讨论.

| Abstract: | Prices of luminescent organic rare earth complexes are dear due to big rare earth content and hence highly preparative cost.With reference to luminescent mechanism of inorganic materials,Sr-Eu phthalate was prepared by blending Eu~(3 ) into Strontium phthalate and low rare earth content luminescence had been achieved.Though consumption of Eu~(3 ) ion is dramatically reduced,the fluorescence intensity of the product is remarkably higher than pure organic rare earth complex Europium phthalate.The effects of preparation conditions such as temperature,pH and Eu-Sr proportion,on the fluorescence intensity of the product are briefly discussed. |
