Lanthanum phosphate (LaPO ) nanostructures with different morphologies were prepared by a facile solution-precipitation process. The effect of different reaction conditions on the morphology of nanostructures was studied. When the molar ratio of La :H PO 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 H PO to ionic surfactants, such as SDS and CTAB, was varied. In addition, Eu doped and Ce /Tb co-doped LaPO nanostructures showed morphology evolution similar to undoped LaPO nanostr..View full abstract
