Abstract: (1488 Views)
In the present work, tungsten oxide nanoparticles (WO3) were synthesized using the simple and low-cost sol-gel method. The UV-Vis optical spectrometer was used to determine the absorption and transmission spectra of tungsten nanoparticles. X-ray diffraction (XRD) technique was used to investigate the crystalline structure. XRD pattern of the sample shows formation of WO3 with hexagonal structure. The crystallite size, micro strain and the specific surface area of the nanoparticles was estimated from XRD analysis. Optical bandgap and the band structure of the sample were evaluated from UV-Vis spectroscopy.
