Microstructural, dielectric and spectroscopic properties of Li2O–Nb2O5–ZrO2–SiO2 glass system crystallized with V2O5

Photostimulated optical effects and some related features of CuO mixed Li2O–Nb2O5–ZrO2–SiO2 glass ceramics

“…The observed dielectric relaxation effects in Li 2 O-Nb 2 O 5 -ZrO 2 -SiO 2 glasses crystallized with different concentrations of CuO may be attributed to the association of octahedrally positioned Cu 2+ ions with a pair of cationic vacancies as observed in a number of conventional glasses, glass ceramics and crystals that contain divalent positive ions as reported before [46,47].…”

The role of vanadium valence states and coordination on electrical conduction in lithium iodide borate glasses mixed with small concentration of silver iodide

“…The V 4+ ions form vanadyl complexes (VO 2+ ), act as modifiers and distort the glass network similar to lithium ions. In this type of glasses there is also a possibility to reduce a small fraction of V 5+ ions to diamagnetic V 3+ ions [19][20][21]. Fig.…”

Effect of P2O5 on optical parameters of (25−x) CaO–xP2O5–B2O3–SiO2–ZnO sol–gel glasses: a theoretical assessment

“…Lots of research has been carried out on borosilicate glasses due to their wide applications as electrodes, sealants, planar optical wave-guides, optical lenses and glass fibers [1][2][3][4]. As compared to the borosilicate glasses, the phosphate glasses remain amorphous even after accommodating higher concentrations of transition ions [5].…”
