“…Glasses without crystalline inclusions were obtained in a small range of compositions, containing high amount of WO 3 (60-75 mol% WO 3 ). In the supercooled compositions, situated near the boundary of glass formation ZnWO 4 and Bi 2 WO 6 were identified. Two parent compositions: 20ZnO·10Bi 2 O 3 ·70WO 3 (Fig.…”

“…7(a) 2− anions respectively [28]. The absorption band at 685 cm −1 assigned to the asymmetric vibration of Mo-O-Mo bond of the condensed molybdate anions [29] and the absorption band at around 840 cm −1 is attributed to the stretching vibration of MoO 4 2− anions [30]. indicate that due to heat-treatment the MoO 4 2− anions are transformed to more complex structural units such as interlinked MoO 6 octahedral and MoO 4 tetrahedral units.…”
“…It is high possible that the non-bridging oxygens are also created with initial addition of gadolinium oxide, but their characteristic high-frequency vibrations are suppressed by the local densification, or by the lack of a dominant structural signature in the reorganized network [36].…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
