The effects of Ag dopant on the structural and optical properties were studied by an X-ray diffractometer (XRD), a transmission electron microscope (TEM), an X-ray photoelectron spectroscopy (XPS) analyzer and a UV-visible spectrometer. The XRD patterns were specified as crystalline structure of Russellite Bi<inf>2</inf>WO<inf>6</inf>. TEM images revealed the presence of the products in the shape of nanoplates. The Bi<inf>2</inf>WO<inf>6</inf> and 3 mol % Ag doped Bi<inf>2</inf>WO<inf>6</inf> show strong absorption in the visible light region with the energy gaps of 3.34 and 3.42 eV, respectively.
