-
BaW4 nanoparticles of wire,rod,and hollow spherical shapes were prepared in different microemulsion systems with octane as the oil,and undecylenic acid and/or dodecylamine as the surfactants.The powder was characterized by XRD,TEM and HRTEM.The Raman spectra of the BaWO4 nanowires and hollow BaWO4 spherical particles were also presented.This method may be extended to prepare novel nanostructures of other tungstates.
