摘要：
The influence of 8 MeV electron beam irradiation on the structural and optical properties of silver tungstate (alpha-Ag2WO4) nanoparticles synthesized by chemical precipitation method was investigated. The dose dependent effect of electron irradiation was investigated by various characterization techniques such as, X-ray diffraction, scanning electron microscopy, UV-vis absorption spectroscopy, photoluminescence and Raman spectroscopy. Systematic studies confirm that electron beam irradiation induces non-stoichiometry, defects and particle size variation on alpha-Ag2WO4, which in turn results changes in optical band gap, photoluminescence spectra and Raman bands.
