Influence of Y2O3 on structural and optical properties of SiO2–BaO–ZnO–xB2O3–(10−x) Y2O3 glasses and glass ceramics

Effect of modifiers field strength on optical, structural and mechanical properties of lanthanum borosilicate glasses

“…When the ionicity of oxygen atoms is increased by converting them from bridging to non-bridging, then the top of valence band is raised resulting in reduced energy gap [39]. It is well reported in the literature that the introduction of heavy metals like barium in glass composition decreases the optical band gap [40]. The change in optical band gap is attributed to the structural changes due to occupancy at different sites by cations.…”

Structural and optical properties of 30Li2O–55B2O3–5ZnO–xTiO2–(10−x)V2O5, (0≤x≤10) glasses

“…Lots of research has been done on the heavy metal oxide containing ternary and quaternary glasses due to their application as reflecting windows, ray absorbers, optical filters as well as mechanical sensors [4][5][6][7][8]. In addition to this, heavy metal oxide glasses exhibit good chemical durability and non-linear optical properties [4,5].…”

“…Transition metal oxides containing borate glasses find a wide range of applications in solar energy converters and solid state lasers [7][8][9]. The presence of transition metal oxides in glass composition modifies the properties of glasses due to variable transition states which formed locally different structural units.…”

Antibacterial and anticancerous drug loading kinetics for (10-x)CuO-xZnO-20CaO-60SiO2-10P2O5 (2 ≤ x ≤ 8) mesoporous bioactive glasses

“…5, peak at position 550-590 cm −1 represents Si-O-Si bending whereas peak at 740-760 cm −1 represents the presence of P-O-P stretching. In addition to this, prominent peak of silicate [51][52][53]. An increase in pH and silica formation layer is observed leading to precipitation of CaO-P 2 O 5 rich layer followed by the occurrence of crystallization causing to form apatite layer.…”
