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
