Due to the low melting temperature, the glazes based on the Bi2O3-B2O3-ZnO system are used as coatings on the surface of industrial glass substrates. Moreover, the composition of these coatings does not contain PbO, meeting the optical and environmental properties requirements. In this study, TiO2 was used in the Bi2O3-B2O3-ZnO glaze system to improve its photocatalytic ability. This can be considered a four – component glass system Bi2O3-B2O3-ZnO-TiO2. The heating microscopy results show that the melting temperature of the glaze system is 606 °C. The Fourier transform infrared spectroscopy results show that the TiO2 polyhedra are located independently in the structure without participating in forming a glass network. Thanks to that, the photocatalytic properties of TiO2 are maintained. The X-ray diffraction patterns results show that the formed TiO2 nanocrystals are rutile and anatase crystals. The results of determining the band gap energy using UV-Vis show that the band gap energy of the base glaze system increases with the addition of TiO2. The methylene blue decomposition results also showed that the ability to decompose organic increased when TiO2 was added to the glaze coating. The characteristics such as melting temperature, microstructure, and photocatalytic capacity of Bi2O3-B2O3-ZnO-TiO2 white glazes (5 and 10 % weight of TiO2) also were indicated in this paper.

“…[1][2][3][4] Furthermore, they can be used for radiation shielding properties which reduce primary and scattered radiation. [5][6][7][8] Glasses are the products of rapidly cooled molten masses that turn into amorphous solids. The production of these glasses has led to the formation of a continuous polymeric network which includes the structural units of the network formers.…”

Gadolinium sodium silicoborate glasses doped with samarium ion (Sm:GNSB) are prepared by the melt quenching technique. The glasses are studied for their physical, optical, and luminescence properties. The density, molar volume, and refractive index of glass are investigated as a function of Sm2O3 concentrations. Addition of Sm3+ ions in the glass matrix shows several absorption peaks in the visible and near‐infrared region, verified by the absorption spectra. The energy transfer from Gd3+ to Sm3+ is observed by photoluminescence (PL) emission spectra, which illustrates the strongest emission occurring at 600 nm (4G5/2 → 6H7/2). The PL decay time of 600 nm emission under 403 nm excitation decreases with increasing Sm2O3 concentrations. The color coordinates of the International Commission on Illumination chromaticity show different shades of orange color under different excitations. The result of radioluminescence shows a similar trend to PL emission spectra. Glasses doped with Sm3+ ions find potential use as an orange color‐emitting optoelectronic device application.
