title: Thermoluminescence and optically stimulated luminescence properties of the 0.5P₂O₅-xBaO-(0.5-x)Li₂O glass systems.
abstract: Thermoluminescence and optically stimulated luminescence properties of phosphate glasses doped with BaO and Li(2)O at various concentrations were studied. Lithium-doped glasses show a broad TL peak in the 200-300°C region with poor dosimetric characteristics. Barium-doped glasses feature at least two TL peaks, approximately at 200 and 400°C, which were attributed to Ba(2+) ions. They also produce a fast-decaying OSL signal correlated with the lower-temperature TL peak. Responses of both TL emissions to radiation doses up to 100 Gy are linear (R² >0.99). Due to its encouraging characteristics such as acceptable batch homogeneity, good measurement reproducibility and weak signal fading, the P₂O₅-xBaO glass can be considered as a candidate material for dosimetry in the high-dose range (>10 Gy).
