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 adoi:10.4236/ns.2014.612094 fatcat:p5sa3nc3rrbifi2jym7encuypm
