摘要： 以EDTA为螯合剂,采用络合共沉淀法合成了纳米级镱、钬共掺杂的氟化钇钠上转换荧光材料.所合成的纳米材料颗粒均匀,分散性好.通过调节EDTA的加入量,可在41～148nm范围内调控纳米颗粒的大小.在980nm红外激光器照射下,肉眼可观察到明亮的上转换荧光,对发光机理进行了探讨.

Abstract: Nanocrystals of up-conversion phosphor, ytterbium and holmium co-doped sodium yttrium fluoride were prepared by a co-precipitation method in the presence of EDTA. Nanocrystals of different sizes with an average diameter of 148, 83 and 41 nm were obtained in defferent molar ratios of EDTA to total Ln3+(Y3+, Yb3+, Er3+) of 0, 0.5 and 1, respectively. Up-conversion fluorescent properties of the nanoparticles were also examined.

Key words: Up-conversion fluorescence, Nanocrystal material, Ytterbium, Holmium, Sodium yttrium fluoride
