As part of a general study of the thermoluminescence (TL) of quartz, we have examined the 3-D spectra of samples of quartz extracted from a variety of sediments. Blue emission at about 2.6eV/475nm, which is the photon energy region commonly used in luminescence dating, seems ubiquitous. Significant emission in the red, ~1.9eV/650nm, has been found at most glow temperatures in all of our samples of...
The thermoluminescence and related properties of a specific Australian quartz are considered, using both original experiments and data from the literature on comparable systems. It is concluded that the rapidly-bleaching peak at about 305°C in the glow curve and the peaks at 220, 180 and 100°C, which all emit at wavelengths below about 430 nm in this quartz, form a family , the electron traps...
