Luminescence Characteristics of Feldspar from Nigeria


The luminescence characteristics of feldspar from Nigeria were investigated. Without preheat treatment, the TL glow curve exhibited two peaks at 136°C and 175°C. When preheated to a temperature of 200°C only one peak was observed at 240°C. The highest net IRSL intensity was obtained for a stimulation temperature of 250°C. The TL signal is reduced by IR stimulation, and the longer the stimulation the more pronounced the effect. The dose response curves for both the TL and the IRSL showed a linear relationship for the doses considered in the study. Dose recovery test performed using the SAR method showed consistency with given dose for both TL and IRSL.
