摘要：Rare earth （La, Nd and Tb） oxides with one-dimensional micro/nanostmcatres were synthesized hydrothermally under facile and mild conditions with two surfactants, and characterized by X-ray diffraction （XRD）, thermal gravimetry （TG）, scanning electron microscopy （SEM）, transmission electron microscopy （TEM） and photoluminescence. The results showed that the synthesized rare earth oxides behaved regular nano- and micro-scale structures. And the morphologies of samples depended on the radii of rare earth ions, with the help of two sur- factants of sodium dodecyl sulfonic and PEG 600. Nanocrystalline La2O3：Eu^3＋ possessed good photoluminescence （PL） property and might be used as a nanosized phosphor, its PL intensity was akered by the doping Eu^3＋ concentration and the optimum concentration of Eu^3＋ was 3 mol.%. In comparison with bulk Eu^3＋/La2O3, Eu^3＋/nano-La2O3 showed better photoluminescence property, nearly equal to that of nanocrtstalline La2O3：Eu^3＋. Tb4O7 microwires showed interesting photoluminescence properties.
