Thermoluminescence response of nano gold doped lithium borate glass subjected to photon irradiation

This study investigated thermoluminescence (TL) properties of undoped and gold nano-particle doped lithium borate glass subjected to Co-60 gamma irradiation. The TL properties of both glasses were studied and compared in terms of TL glow curves, linearity, sensitivity and reproducibility. A number o...
