Annealing Effects on the Thermoluminescence Characteristics of LBP:Au Glass Exposed to Co-60 Gamma Rays

Abstract Four Lithium-Carbo-Borate glass samples (named as LBP:Au glass) at fixed phosphorous (P) content (0.4 mol%) and various gold (Au) doping levels (0.02-0.08 mol%) were prepared via the melt-quenching approach. The morphology and amorphous phases of the obtained samples were verified by XRD and FESEM analysis. Additionally, the varying Au contents dependent thermoluminescence (TL) property of the glasses were measured under the exposure of 50 Gy Co-60 γ-ray irradiations. The synthesised glasses showed good transparency and surface homogeneity. The glasses pre-irradiated annealing procedure was conducted easily and efficiently. The sample made with Au of 0.06 mol% displayed the best TL characteristics, making it potential for radiation dosimeters building.
