Abstract
AbstractThermoluminescence (TL) properties of pulverized SiO2:V monoliths synthesized by a solgel method, and annealed at 1273 K during 12 h under air, are presented in this work. Characteristics TL glow curves display a complex shape with at least three maxima located at ˜379, ˜543 and ˜591K. The TL total signal exhibited a linear behavior for doses below 400 Gy. The integrated TL fades down 26 % after 3 h elapsed between irradiation and the corresponding TL readout. These results lead to conclude that annealed SiO2:V is a promising material for ionizing radiation detection and dosimetry.
