Description 343-354
Synthesis of lithium borate glass system was carried using the melt quenching technique with varying concentrations of
magnesium followed by analysing the different characteristics such as physical, structural, optical and thermoluminescene
using various techniques eg. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-Vis
spectroscopy, and Thermoluminescence (TL). The obtained XRD pattern confirmed the amorphous nature of the prepared
samples. Relevant physical parameters have been evaluated to study the response of these properties with respect to
magnesium content. The density and molar volume values showed that the network structure changed with increasing
magnesium content. It is evident from the FTIR spectra that the network of the prepared samples predominantly contains
BO3 and BO4 units. The UV-vis spectra confirmed a decrease in the direct and indirect band gap values with increase in
MgO content. Optical parameters namely refractive index, electronic polarizability, reflection loss and dielectric constant
were also calculated and found to be in good correlation with other studies. Following gamma rays irradiation with different
doses, TL glow curves of prepared glasses were analysed. Deconvolution of TL glow curves was done using glow curve
convolution deconvolution (GCCD) function and trapping parameters of isolated peaks viz. activation energy and frequency
factor have been determined.
