Using a combination of UV–visible spectroscopy and electronic structure calculations, we
have characterized the electronic structures and optical properties of AWO4 (A= Mn, Co, Ni …

Divalent metal tungstates, MWO4, with wolframite (M= Zn and Mg) and scheelite (M= Ca and
Sr) structures were prepared using a conventional solid state reaction method. Their …

The electronic band-structure and band-gap dependence on the d character of A 2+ cation
in A WO 4 wolframite-type oxides is investigated for different compounds (A= Mg, Zn, Cd …

We have carried out optical-absorption and reflectance measurements at room temperature
in single crystals of AWO 4 tungstates (A= Ba, Ca, Cd, Cu, Pb, Sr, and Zn). From the …

Transition-metal tungstates MWO4 (M= Co, Ni, Cu, Zn) have applications in many areas,
including supercapacitors. A good understanding of the electronic structure is essential to …

The electronic structures for cubic WO 3, LiWO 3, NaWO 3, HWO 3, H 2 WO 3, and
hexagonal WO 3 have been calculated. The calculations rely on the local approximation to …

Ab initio calculations based on the density-functional theory have been employed to study
the electronic and magnetic properties of copper tungstate CuWO4, as well as its optical …

In previous work, we studied the electronic structure of several molybdate and tungstate
crystals having the scheelite structure. The wolframite structure is another common form for …

Microscopic optical (absorption and reflection) and ultraviolet photoelectron spectroscopy
(UPS) measurements were performed on single microcrystals of transition-metal tungstates …

X-ray photoelectron spectroscopy (XPS), X-ray emission spectroscopy (XES) and near-edge
X-ray absorption fine structure (NEXAFS) methods were applied to study the electronic …
