WebJun 1, 1997 · The structure of a low-temperature form of tungsten trioxide,e-WO3, has been determined for the first time. Earlier inconclusive evidence for ferroelectricity in this form is confirmed. There are at least six forms of WO3, bute-WO3is the only form now shown to be acentric. The structure analysis ofe-WO3was based primarily on Rietveld analysis of high … WebApr 24, 2013 · The electronic structure of single-crystal WO3 and Na0.67WO3 (a sodium-tungsten bronze) has been measured using soft x-ray absorption and resonant soft x-ray emission oxygen K-edge spectroscopies. The spectral features show clear differences in energy and intensity between WO3 and Na0.67WO3. The x-r …
