Abstract

Lanthanum phosphate (LaPO4) nanostructures with different morphologies were prepared by a facile solutiona??precipitation process. The effect of different reaction conditions on the morphology of nanostructures was studied. When the molar ratio of La3+:H3PO4 was around 1:2, 1:20, 1:100, and 1:200, four different morphologies, such as near-spherical, snowflake-like, star-shaped, lens-like nanostructures and short nanorods, were obtained, respectively. Meanwhile, similar shapes developed when the molar ratio of H3PO4 to ionic surfactants, such as SDS and CTAB, was varied. In addition, Eu3+ doped and Ce3+/Tb3+ co-doped LaPO4 nanostructures showed morphology evolution similar to undoped LaPO4 nanostructures. The optical properties of these doped LaPO4 were also characterized.
