Web15 de out. de 2024 · Consequently, in this article, the structure of Eu 2+ doped borosilicate glasses was adjusted by adding the proper Y 2 O 3, and the effect of Y 2 O 3 on the structure and luminescent properties of the glass was investigated. As an analogy, the influence of CaO was also studied. It's known that CaO acts as network modifiers in glass. WebThus, this glass is topologically similar to B 2 O 3 but for the absence of MRO structures like boroxol. There is the critical requirement of planar units like [BO 3/2] for formation of boroxol-like units. The structure of As 2 S 3 or As 2 Se 3 glass is two dimensional, while the structure of elemental glasses like Se is one-dimensional.
Web6 de jun. de 2014 · It shows a crystalline silicate − also called quartz − together with an amorphous silicate, i.e. a glass. Most of the physical properties of these two samples are surprisingly very similar. It is not possible to distinguish the two states from each other just by looking at them. Both samples are optically transparent.

The structure of several network-forming liquids and glasses is considered, where a focus is placed on the detailed information that is made available by using the method of neutron diffraction with isotope substitution (NDIS).
