Glass preparation and temperature-induced crystallization in multicomponent B2O3–PbX2–PbO–Al2O3–WO3–Dy2O3 (X = F, Cl, Br) system

Ultrasonic and structural features of some borosilicate glasses modified with heavy metals

“…The structure of lead sodium borate glasses has received considerable attention due to its peculiarities [1,2]. These glasses have wide technological and industrial advantages when used in the fields of electronics [3], optical lenses with high refractive indices and low dispersion characteristics [4], transparent nuclear radiation shielding windows [5], solar energy technologies [6] and acoustic-optic devices [7,8].…”

Spectroscopic properties of Yb3+ and Er3+ ions in heavy metal glasses

“…Our previously published results for lead borate glasses indicate that values of the glass transition temperature T g varied from 310 • C to 475 • C, dependently on the B 2 O 3 /PbO ratio and the PbF 2 content [23]. For oxide glass, the glass transition temperature T g is close to 440 • C and its value starts to decrease for oxyhalide glass samples with [24]. In this case, the glass transition temperature reduces from 440 • C to 397 • C when B 2 O 3 component was replaced by GeO 2 in the studied PbO-based heavy metal glasses.…”

Optical properties of amorphous Li2O–WO3–B2O3 thin films deposited by electron beam evaporation

“…Nevertheless, the addition of certain transition metal oxides, such as WO 3 , to Li 2 O-B 2 O 3 glass makes them more moisture-resistant; also, the phonon losses can also be minimised to a large extent. Tungsten-containing glasses have been studied due to the favourable properties of tungsten ions, such as high electro-negativity, polarisability, large ion radius, and changeable valence [6,7].…”
