THERMOLUMINESCENCE PARAMETERS OF QUARTZ EXTRACTED FROM BEACH SAND

In this work, the dosimetric characteristics and kinetic parameters of sand samples from a beach on the Caspian Sea coast of eastern Baku were investigated using the TL technique. The TL glow curve of the natural, unheated quartz deconvoluted using the GlowFit program. It was found that, at least three peaks located at 260oC, 318oC, 366oC which corresponds to the electron traps with the depth of 0.96, 0.97 and 1.2 eV respectively. Calculated frequency factor values related to those centers are within the acceptable range and correlates with the figures reported earlier for the variety of sand samples. The glow curves of preheated sand samples exhibit four poorly resolved peaks due to the overlapping of individual peaks at low and high temperature zones. The deconvolution of those glow curves enables us to separate at least five peaks with the Tmax close to the reported earlier in the literature.
