  • Title: Synthesis and characterization of WO3 nanomaterials.
    Author: Pandey NK, Tiwari K, Roy A.
    Journal: J Biomed Nanotechnol; 2011 Feb; 7(1):156-7. PubMed ID: 21485849.
    Abstract:
    This work reports a simple, quick and economical method to prepare WO3 nanomaterials. Prepared tungsten trioxide materials have been sintered at 700 degrees C for three hours. The material has been studied by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). Crystallite size of the WO3 nanostructures obtained by Shearer's formula are between 12 and 72 nm and their grain size by SEM are from 20 to 105 nm. The humidity-sensitive electrical properties of the WO3 nanomaterial have been studied using d.c. measurements.
