Effects of Sm3+ ions on the structural, optical and thermoluminescence properties of MnKB glass system

In this study, the optical, thermoluminescent, structural, and physical characteristics of samarium doped manganese potassium borate glasses were analyzed using diffuse reflectance spectroscopy, thermoluminescence (TL), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy techniques. The glasses were obtained using the well-known melt-quenching process. The XRD patterns confirmed the non-crystalline characteristics of the prepared glasses and numerous structural groups were identified in the glasses based on the FTIR spectra. Physical and optical parameters were evaluated to study their responses to different Sm3+ concentrations. The indirect and direct band gaps were evaluated based on the Tauc's plots. The TL glow curves for the glasses were analyzed after irradiation with different gamma ray doses (10 Gy-10 kGy). Kinetic parameters including the frequency factor and activation energy were determined using the peak shape method.
