Abstract

The atomic structure of nanosized and microcrystalline tungstates MeWO ₄ (Me=Co, Ni, Cu, Zn), synthesized by co-precipitation technique, has been studied by x-ray absorption spectroscopy at the W L₃-edge and Co/Ni/Cu/Zn K-edges, x-ray diffraction, Raman and Fourier transform infrared spectroscopies. The distortion of metal-oxygen octahedra is caused by the electron-lattice coupling and is further enhanced in nanosized tungstates due to formation of the double tungsten-oxygen bonds at the nanoparticle surface.
