Synthesis and characterization of CuO doped lithium magnesium borate glasses for thermoluminescence dosimetry

In the present study, we have fabricate lithium magnesium borate glasses doped with different Cu2+ contents using the melt quench technique. The fabricated nanocomposites were characterized via FTIR, XRD, Raman and DRS analysis. The XRD pattern of all the nanocomposite definite the amorphous nature and the IR spectra revealed the presence of BO3 and BO4 units in the nanocomposites. The fabricated nanocomposites were used for solid state thermoluminescence dosimetry under the gamma radiation (cobalt, Co-60 source). The optimum annealing temperature was found to be 300 degrees C within 60 min. The results revealed that an enhancement in the TL intensity with the increment a certain amount of Cu2+ into the Lithium magnesium borate (LMB) samples. The fabricated nanocomposites show excellent TL intensity, reproducibility and a good linearity with linear regression coefficient of 0.9980 and 0.9949 with the dose range of 1-10 Gy and 10-100 Gy, respectively. These attractive outcomes exhibit that our fabricated nanocomposites can be used in personal, environmental and medical radiation therapy applications in future.
