Thermoluminescence properties of borosilicate glass doped with ZnO

Thermoluminescence (TL) properties of new synthetic borosilicate glass (SiO2-H3BO3-Na2CO3) doped with various concentrations of ZnO are studied. The glasses were prepared by the melt quenching method and irradiated with gamma doses in the range of 0.5-500 Gy. Some properties such as, dose response, minimum detectable dose, reproducibility of the response, thermal and optical fading and IR absorption were studied. Optimum glass composition with a good linear TL gamma dose response over a wide dose range, as well as low fading and excellent reproducibility is obtained. These appealing features indicated that; this new synthetic TL glass material is useful in many radiation detection applications.
