Investigating thermoluminescent properties of nanocrystalline lithium borate doped with dysprosium
2018
AbstractWe investigate the thermoluminescence (TL) properties of nanocrystalline Li2B4O7:Dy. The TL properties of the said phosphor are of great interest as it has an effective atomic number close to that of a biological tissue. The phosphor is synthesized by combustion method and characterized by X-ray diffraction and transmission electron microscopy. When the nanophosphor is exposed to a range of gamma doses using cobalt-60, it exhibits a linear TL response for an extensive range of doses. Further, the reproducibility and batch homogeneity properties are also studied. In conclusion, nanocrystalline Li2B4O7:Dy shows potential as a radiation dosimeter of gamma rays.
