Liquid-like ionic diffusion in solid bismuth oxide revealed by coherent quasielastic neutron scattering
Wind, Julia; Mole, Richard A; Yu, Dehong; Ling, Chris DPublished 2017-01-01The exceptional oxide-ionic conductivity of the high-temperature phase of bismuth oxide gives rise to a characteristic “quasielastic” broadening of its neutron scattering spectrum. We show that the oscillating form of this ...Open AccessArticle -
Local structure adaptations and oxide ionic conductivity in the Type III stability region of (1–x)Bi2O3∙xNb2O5
Wind, Julia; Sharma, Neeraj; Yaremchenko, Aleksey A; Kharton, Vladislav V; Blom, Douglas A; Vogt, Thomas; Ling, Chris DPublished 2018-01-01Starting from a previously published stoichiometric model for the commensurate Type III phase in the (1–x)Bi2O3∙xNb2O5 system, Bi94Nb32O221 (x = 0.254), we have developed a crystal-chemical model of this phase across its ...Open AccessArticle -
Oxygen Dynamics in Transition Metal Doped Bismuth Oxides
Wind, Julia; Mole, R M; Ling, Chris DPublished 2019A detailed quasielastic neutron scattering (QENS) study provides direct insights into the mechanism of ionic conduction in the Type II transition metal-doped bismuth oxides Bi22W5O48, Bi22Nb5O45.5 and Bi22W2.5Nb2.5O46.75. ...Open AccessArticle -
Rational design of a commensurate (3+3)-D modulated structure within the fast-ion conducting stabilized δ-Bi2O3 series
Wind, Julia; Polt, Julia; Zhang, Zhaoming; Blom, Douglas A; Vogt, Thomas; Withers, Ray L; Ling, Chris DPublished 2017-01-01We report the systematic design, preparation, and characterization of the first commensurate member of the oxide-ionic conducting, (3 + 3)-D modulated, Type II phases of doped δ-Bi2O3. The incommensurate Type II modulation ...Open AccessArticle -
Stability and range of the type II Bi1-xWxO1.5+1.5x solid solution
Wind, Julia; Kayser, Paula; Zhang, Zhaoming; Radosavljevic Evans, Ivana; Ling, Chris DPublished 2017-01-01We have established the stability and range of the cubic type II phase of Bi1-xWxO1.5+1.5x using a combination of X-ray diffraction, neutron diffraction and X-ray absorption spectroscopy. Type II is a high temperature ...Open AccessArticle
