摘　　要：本文以聚乙烯吡咯烷酮为基质制得了纳米邻苯二甲酸铽络合物并对其荧光光谱进行了研究 ,结果表明聚乙烯吡咯烷酮中纳米邻苯二甲酸铽络合物主要荧光发射峰的相对强度及峰的半高宽有明显变化 ,并且主峰附近分化出两个峰。Nano-sized terbium(Ⅲ)-phthalic acid complex was prepared in polyvinylpyrrolidone.It′s fluorescent spectrum has been investigated,compared to that of common terbium(Ⅲ)-phthalic acid complex and terbium(Ⅲ)-polyvinylpyrrolidone complex.The results show that fluorescent characteriations of Nano-sized terbium(Ⅲ)-phthalic acid complex is obviously different from that of common terbium(Ⅲ)-phthalic acid complex and terbium(Ⅲ)-polyvinylpyrrolidone.The relative intensity and half-hight width of main emission peaks are obviously varied,two splitting peaks are displayed.
