A component resolved study on the stable signal of Merck alpha-quartz: Tentative correlation among TL peaks, OSL components and EPR signals

In the present work, pre-dosed alpha-quartz is investigated towards its effective applications in retrospective dosimetry and dating as a reference material. The purpose of the study is to find tentative correlations between Thermoluminescence (TL) (high temperature II, (HTTL) peaks), Optically Stimulated Luminescence (OSL) (both continuous wave (CW) and linear modulated (LM)) and Electron Paramagnetic Resonance (EPR). The present work indicates a triple correlation between the fast CW-OSL component and certain peaks of LM-OSL and TL signals, while all these luminescence entities are attributed to the EPR signal with g-value (Lande splitting factor) at 1.9975 called C2(EPR). The present study provides experimental evidence that (i) one TL peak might be the source for more than two LM-OSL components and (ii) even two different II, peaks can contribute to the same OSL component. Furthermore, on the EPR signal, besides the well established Ge center, another un-identified component has been resolved.
