“…The glass also exhibits a very broad band centered at 800 nm and this band is related to the presence of Cu 2+ ions in distorted octahedral coordination [27]. The stability of the optical absorption of this glass after gamma irradiation is related to some shielding behavior of the glass containing CuO towards gamma irradiation.…”

Optical and FT infrared absorption spectroscopic studies were carried out to investigate the spectral properties of prepared undoped and 3d transition metal oxides-doped-strontium borate glasses. The same measurements were repeated after gamma-irradiation of the samples with a dose of 8 Mrad (8  10 4 Gy). The undoped strontium borate glass before irradiation exhibits a broad strong UV absorption which is related to unavoidable trace iron (Fe 3+ ions) impurities contaminated within the raw materials used for the preparation of this glass. Examination of the optical spectra of TMs-doped glasses reveals extra characteristic UV-visible bands due to the respective doping 3d transition metal ions. Gamma irradiation of the undoped strontium borate glass produces induced defects within the UV and visible regions while the TMsdoped glasses reveal limited variations due to shielding effects of some TM ions in this specific host strontium borate doped glasses towards gamma irradiation.Infrared absorption spectra of the prepared glasses reveal characteristic vibrational bands due to both triangular and tetrahedral borate groups within the wavenumber range 1200-1600 cm -1 and 800-1200 cm -1 , respectively. The addition of 3d TM dopants (0.2 %) causes no distinct variations in the main IR vibrational bands because of the low level of TM ions and their housing in the glass network structure as modifiers. Also, gamma irradiation causes no changes in the number or position of the main characteristic IR vibration bands due to the quite stability of the base glass containing high content of heavy metal (Sr 2+ ) cations.

“…Moreover, Rodriguez et al have reported the synthesis of Cr 3+ -and Tm 3+ -doped alkaline silicate glasses [22]. On the other hand, Cu 2+ -doped [23] and V 5+ -doped [24] lithium disilicate glasses have been reported previously. However, to our best knowledge, no work has been devoted to antimony-doped lithium silicates.…”

The hydrothermal synthesis and optical properties of undoped and Sb 3+ -doped lithium metasilicate and lithium disilicate nanomaterials were investigated. The microstructures and morphologies of the synthesized Li 2−2x Sb 2x SiO 3 and Li 2−2x Sb 2x Si 2 O 5 nanoparticles were studied with powder X-ray diffraction and scanning electron microscopy techniques, respectively. The synthesized undoped and doped lithium metasilicate and lithium disilicate nanomaterials, respectively, are isostructural with the standard bulk Li 2 SiO 3 (space group Cmc2 1 ) and Li 2 Si 2 O 5 (space group Ccc2) materials. The electronic absorption and photoluminescence spectra of the synthesized materials are studied. The measured optical properties show dependence on the dopant amounts in the structure.
