摘要
该文以聚乙烯吡咯烷酮为表面活性剂,在无水乙醇中制备了纳米二苯甲酰甲烷钐配合物Sm(DBM)3,并以红外光谱(IR)、透射电镜(TEM)、X 射线衍射(XRD)、荧光光谱(FS)等测试方法对其进行了表征.结果表明,配合物在聚乙烯吡咯烷酮中呈纳米颗粒分散,分散尺度为20～35nm,其主要荧光发射峰的位置、强度、主峰的半高宽等与普通二苯甲酰甲烷钐配合物有明显的区别.
Nano-sized samarium (Ⅲ)-dibenzoyl methane complex was prepared in absolute ethyl alcohol with polyvinylpyrrolidone as surfactant. It was characterized by IR, TEM, XRD and FR. The results show that the nanoparticles of the complex are dispersed in polyvinylpyrrolidone, and the size of the particles is 20～(35 nm). The fluorescence spectrum of nano-sized Sm(DBM)_3 complex is obviously different from that of common Sm(DBM)_3 complex in peak location, intensity and half-height width.
