Thermoluminescence investigations on xY2O3 (60−x)P2O5·40SiO2 vitroceramics

Thermoluminescence properties of xY2O3·(60−x)P2O5·40SiO2 vitroceramic compounds doped with xY2O3 at various concentrations (0≤x≤30 mol%) were studied. Compounds with reduced Y2O3 concentration showed unsatisfactory dosimetric properties, while the vitroceramics composed of 20Y2O3·40P2O5·40SiO2 and 30Y2O3·30P2O5·40SiO2 exhibited bright signals, linear dose response and minimum detectable doses of 16 mGy and 4 mGy, respectively. Moreover, 30 mol% Y2O3 doped vitroceramic exhibited good repeatability, acceptable batch homogeneity and poor fading signal, features that are recommending this material for dosimetry purposes.
