The composition of glass with 40% SiO2, 40% B2O3, 10% V2O5, (10-x)% Fe2O3, and x% Sm2O3 (where x = 0, 2, 4, 6 mol%) was prepared using the melt-quench technique. Various experimental methods such as X-ray diffraction (XRD), Fourier transforms infrared (FTIR) spectroscopy, Raman spectroscopy, UV-visible spectroscopy, and vibrating sample magnetometer (VSM) were used to characterize the structural, optical, and magnetic properties of the as-prepared glasses. The addition of Sm2O3 increased the glass density nonlinearly, and the optical band gap was in the semiconducting range (2.2-2.6 eV). These glasses can potentially be used in hyperthermia treatment as thermoseeds.
The glass composition 40 SiO2 -40 B2O3 -10 V2O5 -(10-x) Fe2O3 - (x) Sm2O3 with x = 0, 2, 4, 6 mol% are prepared using the melt-quench technique. The as-prepared glasses are characterised by different experimental methods such as X-ray diffraction (XRD), Fourier transforms infrared (FTIR) spectroscopy, Raman spectroscopy, UV-visible spectroscopy and vibrating sample magnetometer (VSM) for their structural, optical and magnetic properties. The replacement of Fe2O3 by Sm2O3 increases the density of the glasses with decreasing molar volume nonlinearly. Raman, FTIR and XRD spectra indicate that samarium oxide addition increases the glass formation tendency up to 6 mol%. The optical band gap increases with Sm2O3 concentration and is in the semiconducting range, i.e., 2.2-2.6 eV. The present glasses and glass ceramics can be used as thermoseeds for hyperthermia treatment.
