摘　　要：本文以聚乙烯吡咯烷酮为表面活性剂,在水溶液中合成了纳米均苯三甲酸铽配合物。并通过红外光谱、透射电镜、荧光光谱等表征手段对其进行了表征。结果表明,纳米均苯三甲酸铽的荧光光谱在主要发射峰的峰位、峰强、半高宽和最强峰与次强峰的强度之比等方面与普通均苯三甲酸铽有明显差别。Nano-sized terbium(Ⅲ)-trimesic acid complex has been prepared in aqueous solution with polyvinylpyrrolidone as surfactant.Elemental analysis,rare earth coordination titration show that the complexes have the composition of TbL·6H2O(H3L=BTC).IR spectra show that the Tb3+ ions are bounded with the oxygen atoms of trimesic acid.TEM show that nano-rods of terbium(Ⅲ)-trimesic acid complex has been prepared in polyvinylpyrrolidone.The fluorescence spectrum of nano-sized terbium(Ⅲ)-trimesic acid complex is obviously different from that of common terbium(Ⅲ)-trimesic acid complex in peak location,intensity and half-height width.
