Gamma Rays Interactions with Strontium Borate Glasses Doped with First-Row Transition Metal Oxides

Abstract: 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 t… Show more

“…The observed peaks in the second region at 708-713 cm -1 are attributed to the combined vibrations of the BO3 (Vijay et al 2015) and PbO4 groups (Varshneya 1994), bending vibration of the B-O-B linkage in the borate network (ElBatal et al 2014;Kamitsos et al 1987Kamitsos et al , 1981, and the stretching mode of Ge-O-Ge bonds in GeO6 units (Narendrudu et al 2016;Tenny and Wong 1972).…”

“…The absorption peak appeared in the wave number range 1384-1391 cm -1 possibly due to the asymmetric relaxation of the B-O bond of the triangular [BO3] units (Varshneya 1994;ElBatal et al 2014;Kamitsos et al 1987Kamitsos et al , 1981Doweidar and Oraby 1997) stretching vibrations of the borate triangles with non-bridging oxygen (NBO) in various borate groups (Chelcea et al 2011), and the asymmetric stretching vibration modes of Ge-O-Ge bonds (Narendrudu et al 2016). Moreover, in Fig.…”
