文摘

SnO2 nanoparticles doped lithium potassium borate with Cu-doped was prepared by melt-quenching technique. The field emission scanning electron microscope was used to examine morphology of samples. The TLD-Reader 4500 was used to measurement of thermoluminescence. The glow curves position of Cu-doped and co-doped SnO2 glass were recorded at about 205 °C and 215 °C respectively. The linear relationship of dose-TL intensity was observed for both samples. The TLD sensitivity shows that the co-doped SnO2 glass has almost 6 time higher sensitivity compared to Cu-doped glass. It was found that the theoretical calculations are in good agreement with the experimental results for relative energy response. The activation energy and frequency factor of TL glow peak are determined by using the peak shape method.
