Abstract
Abstract: The SiO2 nanoparticles have been extracted from clay by the sol-gel method and mixed with magnesium oxide. The prepared samples were characterized using XRD, IR, and XRF. Their thermoluminescence properties were examined using an ultraviolet (UV) source of 254nm. The samples display two peaks at 203oC and 307oC for 0.1% SiO2 whereas for 0.7% (SiO2) at 236°C and 357°C. The dose-response was linear with UV energy in the range from 100µJ/cm2 up to 7700µJ/cm2. Clay is a natural, low-cost material, available in large quantities in the south of Libya, and has the potential to be used as a TL material.
