借助超声技术采用一种简便易行的共沉淀方法制备出聚偏二氟乙烯(PVDF)/钇铕稀土氧化物((Y0.97Eu0.03)2O3)纳米粒子发光纳米复合材料.复合材料的断面形貌和(Y0.97Eu0.03)2O3纳米粒子在PVDF基体中的分散状态通过扫描电子显微镜(SEM)进行了研究,其发光性质通过荧光光谱进行表征.SEM结果表明: 当(Y0.97Eu0.03)2O3纳米粒子添加量在1%～5%时,(Y0.97Eu0.03)2O3纳米粒子在PVDF基体中形成尺寸在50 nm～2 μm的团聚体, 其尺寸随(Y0.97Eu0.03)2O3添加量增加而增大;当(Y0.97Eu0.03)2O3添加量小于1%时, (Y0.97Eu0.03)2O3纳米粒子在PVDF基体中实现了较好分散.发光光谱结果表明制备的纳米复合材料具有明显的红光发射特征,对应于(Y0.97Eu0.03)2O3纳米粒子的本征发射.制备的高分子发光纳米复合材料将来有望在光学材料中获得应用.

In this communication,the poly(vinylidene difluoride) (PVDF)/(Y0.97Eu0.03)2O3 rare-earth nanocomposites were prepared by a facile co-precipitation method with the aid of ultrasonic technique. The cross sections of the nanocomposite were observed by scanning electron microscopy (SEM),and the luminescent properties of the nanocomposites were studied by fluorescence spectroscopy. The SEM results showed that the (Y0.97Eu0.03)2O3 nano-particles were dispersed in PVDF matrix as some aggregates with the sizes between 50 nm～2 μm when the mass fraction of (Y0.97Eu0.03)2O3 was between 1% and 5%; while the (Y0.97Eu0.03)2O3 particles were better dispersed in the matrix when the (Y0.97Eu0.03)2O3 mass fraction was lower than 1%. The luminescence spectra showed a characteristic red-emitting of PVDF/(Y0.97Eu0.03)2O3 nanocomposites at 612 nm,corresponding to the intrinsic luminescence of the Eu3+ ion in (Y0.97Eu0.03)2O3 nanoparticles. The prepared rare-earth nanocomposites with unique optical characteristic may be used as optical materials in the future.
