“…[3,7,28] investigated natural and synthetic quartz samples by CL microscopy and spectroscopy, discussing the state of knowledge and summarizing some principal ideas about the origin of the different CL properties of quartz of various origin. RL (radioluminescence), TL (thermoluminescence) and OSL (optical stimulated luminescence) were also used as luminescence tools, working with different excitation sources to study quartz luminescence properties in different research fields [33,[42][43][44][45][46][47].…”

Quartz from La Sassa (Tuscany, Italy) presents a unique luminescence related to intrinsic and extrinsic defects in the crystal lattice due to the growth mechanisms in hydrothermal conditions. The bright fluorescence under the UV lamp was apparent to collectors since the early 1970s, and it entered the literature as a reference case of yellow-luminescent quartz. Early reports present the history of the discovery, the geological context, and preliminary luminescence measurements of the quartz nodules, suggesting various activators as potentially responsible of the peculiar luminescence effects: uranyl groups (UO22+), rare earths (Tb3+, Eu3+, Dy3+, Sm3+, Ce3+) and polycyclic aromatic compounds (PAH). Here, we report a full investigation of the La Sassa material, by a multi-analytical approach encompassing cathodoluminescence optical microscopy (OM-CL), laser-induced fluorescence (LIF), wavelength resolved thermally stimulated luminescence (WR-TSL), trace elements analysis by mass spectrometry (ICP-MS) and Raman spectroscopy (RS). The results provide a significant step forward in the interpretation of the luminescence mechanisms: the main luminescent centres are identified as alkali-compensated (mainly Li+ and Na+, K+ and H+) aluminum [AlO4/M+]0 centres substituting for Si, where the recombination of a self-trapped exciton (STE) or an electron at a nonbridging oxygen hole centre (NBOHC) are active.

“…In the given study, in order to determine the TL kinetic parameters of natural quartzite, the TLanal programme [21] was used as a CGCD method. This program has been used lot of studies [22][23][24]. After many attempts, it was found that the structure of the natural quartzite sample could be defined by at least eight glow curves ( Figure 5).…”

In the present study, the thermoluminescence characteristics of natural quartzite collected from Karaisalı (Adana) in Turkey were investigated after β irradiation at room temperature with the purpose to use as radiation dosimetry. The glow curve of quartzite mineral shows two peaks at 110 o C and 250 o C and a shoulder at 375 o C, explicitly. The resulting peaks, which were examined using the computer glow curve deconvulation (CGCD) method, were deconvuluted and kinetic parameters (activation energy Ea, frequency factor (s) and kinetic degree (b)) were determined. After CGCD methods, it was seen that the glow curve suporposed at least eight peaks. Additionally, kinetic parameters were determined using by Arrhenius plot obtained from initial rise (IR) method. In this study, it is shown that there is a correspondence between kinetic parameters calculated by IR method and peaks deconvoluated by CGCD technique in low temperature region (P1-P3). Additionally, reusability test was conducted to investigate its usability as a dosimetric material, and a change of 2% was observed in the results of 10 repeated times. Besides to the characterization of this sample X-ray diffraction (XRD) and scanning electron microscopy (SEM)-energy dispersive X-ray (EDX) results were investigated.

In the present study, soil samples of Seyhan Dam Lake Terraces were collected and then pure quartz samples were separated using various separation methods. The quartz samples were characterized using X-ray diffraction (XRD) and scanning electron microscopy – energy dispersive X-ray spectroscopy (SEM-EDX) methods. Thermoluminescence (TL) measurements were carried out using lexsyg smart TL – optically stimulated luminescence (OSL) reader with a constant heating rate of 1 °C/s from room temperature to 450 °C. Beta dose response of the samples were investigated in the dose range from 1 to 10 Gy and the linear dose response range was determined as 1–5 Gy. Computerized glow curve deconvolution (CGCD), peak shape, and isothermal decay (ID) methods were used to determine activation energy (E), order of kinetics (b), and frequency factor (s) of the samples. Furthermore, in this study, minimum detectable dose values of the quartz samples were also determined.
