Anisotropy of optical properties of scheelite tungstates in the fundamental absorption region
Abstract
Reflectivity spectra of single crystals of Ca, Ba and Pb tungstates in the energy range 4-30 eV are presented. Anisotropy of scheelite structure is studied on this set of crystals for their different orientations using polarised synchrotron radiation. Common features of the spectra are discussed in terms of electronic transitions within molecular complex WO 4.
