Abstract
Nanoparticles of zirconium(IV) tungstate are prepared by chemical co-precipitation method. The
characterizations have been carried out by TG/DTA, DSC, AFM, XRD, FTIR and UV-Vis spectrum. PL
spectrum shows two emission bands at 350 nm and at 477 nm. The effects of frequency on the dielectric
behavior and ac electrical conductivity have been studied. The dielectric constant is found to be 119.43 at
1MHz. The ac conductivity is 7.29x10-8S/cm.
