Description
Summary:Silver tungstate ( α -Ag 2 WO 4 ) nanoparticles were synthesized by chemical precipitation method. Thermodynamic stability of the α -Ag 2 WO 4 nanoparticles was studied by thermogravimetric and differential thermal analysis. These nanoparticles were structurally characterized by X-ray diffraction, Fourier transform infrared spectroscopy and Raman spectroscopy. The structure and morphology of these nanoparticles were studied by scanning electron microscopy and high-resolution transmission electron microscopy. The composition of nanoparticles near and at the surface was estimated by using energy-dispersive X-ray analysis. The optical properties of these nanoparticles were investigated by UV–Visible as well as photoluminescence spectroscopy. The effects of calcination temperature on the geometric parameters and optical properties of α -Ag 2 WO 4 nanoparticle samples was also investigated.
