摘要
在体积比为1∶1的乙醇水溶液中,合成了钐(Sm)-对苯二甲酸(1,4-bdc)二元纳米配合物Sm(1,4-bdc)2.3H2O.利用元素分析(CHN)、红外光谱(FTIR)、热分析(DSC-TGA)、紫外-可见分光光度计(UV-Vis)、荧光分光光度计(FS)和透射电镜(TEM)等分析手段对纳米配合物的组成、光学性质、形貌和粒径进行了分析与表征.实验结果表明,在二元纳米配合物中,对苯二甲酸的羧基氧与Sm3+配位;此二元纳米配合物具有一定的荧光性能,形貌为球形,粒径范围3.8～68.9nm,平均粒径为26.3nm.
The nano complex Sm（i,4-Hbdc） · 2H20 of SmCI3 · 6Hz O with terephthalic acid was synthe- sized in ethanol water which was composed of 1 ： 1 （V/V）. The composition, optical properties, mor- phology and size of the nano complex were analyzed and characterized by EA, FTIR, DSC-TGA, UV-Vis, FS and TEM, respectively. The results showed that the oxygen atoms of carboxyl group from tereph- thalic acid is coordinated with Sm3＋ ions in the nano complex, and it has some fluorescence property. And the size of the nano complex particles is between 3.8nm and 68. 9nm, and each particle is the layered structure,the interlayer spacing of them is about 26.3nm.
