Synthesis and Characterization of Novel Nanocrystalline Zirconium (IV) Tungstate Semiconductor

Nanocrystalline zirconium (IV) tungstate is prepared by chemical coprecipitation method using ethylene diamine tetra acetic acid as the templating agent. Elemental composition is determined by EDS. The characteristic bonding position is identified using FTIR. XRD is used to find the theoritical value of size and phase identification using JCPDS. Morphology is examined using SEM and HRTEM. UV absorption at 260 nm corresponds to an energy gap of 4.48 eV, characteristic of semiconducting nanoparticles.
