The present study examines radiofluorescence (RF) emissions in quartz from parent rocks (igneous plutonic and volcanic) and sediments of different provenances, which represent a range of optically stimulated luminescence (OSL) and thermoluminescence (TL) sensitivities observed in nature. OSL and TL (110 °C peak) sensitivities of quartz have been successfully used for sediment provenance analysis, but the considerable sensitivity variations are still poorly understood in terms of charge traps and recombination centers. In the studied samples, the RF spectra obtained at room temperature and usin

Abstract The estimation of firing temperature of ceramics using methods based on pre-dose sensitization of the 110°C TL peak of quartz have yielded incoherent results. Recently the fast component of the CW-OSL of quartz has been observed to have pre-dose characteristics similar to that of the 110°C TL peak. The motivation for this study has been to look into the feasibility of this signal, the OSL counter part of pre-dosed TL emission, for the firing temperature identification. The variation in the sensitization ratio of the TL and OSL emissions with different heating temperatures was also uti

Abstract Luminescence dosimetry assumes samples of a given material with diverse provenances behave in a predictable manner, allowing a standardised testing protocol, such as SAR for quartz, to be employed. This article demonstrates that distinct salt products derived from a single manufacturer’s feedstock retain comparable luminescence behaviour. This is the basis of a standardised test protocol: uniting testing procedures which have been shown to be individually applicable. Generalization across samples from different manufacturers and processes is currently under investigation. Luminescent

Abstract AlN is a wide band gap material with promising properties for dosimetric applications, especially in UV dosimetry. In the present research, the thermoluminescence method is used in order to better understand sunlight and X-ray irradiation effects on yttria doped AlN ceramics. In general, the TL response is characterised by a broad TL peak with maxima around 400–450 K and a TL emission spectrum with UV (400 nm), Blue (480 nm) and Red (600 nm) bands. Compared to the X-ray irradiation, sunlight irradiation creates a wider TL glow curve peak with a maximum shifted to higher temperatures b

Thus, crystal defect is easy to be formed without some dopant using the μ-PD method.

Excitation functions for the reactions 197 Au(p,n) 197g Hg and 197 Au(p,n) 197m Hg have been measured over the energy ranges from threshold up to 20 MeV using stacked foil activation technique. The isomeric cross-section ratio σm/(σm+σg) for the formation of 197g, m Hg was determined. The excitation functions and isomeric cross-section ratios were calculated for the reactions 197 Au(p,n) 197g,m Hg , 197 Au(p,2n) 196 Hg , 197 Au(p,3n) 195g,m Hg , 197 Au(p,4n) 194 Hg , 197 Au(p,5n) 193g,m Hg , 197 Au (α, n )200 Tl , 197 Au (α, 2n )199 Tl , 197 Au (α, 3n )198g,m Tl , 197 Au (α, 4n )197 Tl and 197

Abstract Olivine has so far attracted limited attention as a potential luminescence dosimeter. In particular, there is a dearth of information concerning the luminescence properties of geochemically characterised, pure olivine samples. Six well-characterised olivine samples from four intraplate settings are investigated in this study, including emission wavelengths and intensities, growth of signal with absorbed dose, signal stability and recovery of a given dose with a single aliquot regeneration (SAR) protocol. All tested olivines share a low-temperature (90–100°C) UV/blue thermoluminescence

Abstract This paper investigates the low-frequency noise (LFN) utilizing 1/f noise and random telegraph noise (RTN) characteristics of Hf-based metal/oxide/nitride/oxide/silicon (MONOS) nonvolatile memory devices with HfO2 and HfON tunneling layers (TLs). The LFN spectral density (S I D ) was investigated to evaluate the interface characteristics before and after programming/erasing cycles of 104. The devices show similar slopes of ∼1/f in all frequency regions. Although the HfON TL shows high S I D compared to the HfO2 TL, the increased ratio is 10 which is low compared to the HfO2 TL ratio o

In order to evaluate the suitability of minerals other than quartz and feldspar for luminescence dating of sediments, luminescence properties from almandine and kyanite relevant for dosimetry such as luminescence signal stability, bleachability by sunlight exposure, and dose response are investigated. Thermoluminescence (TL) signals (UV emission) from almandine aliquots present athermal instability for the entire tested TL temperature range (25 – 450 °C). Almandine also presents a significant infrared stimulated luminescence (IRSL), post-infrared IRSL (post-IR IRSL) and optically stimulated lu

ABSTRACTThe thermoluminiscent properties of MEH-PPV and MDMO-PPV conjugated polymers were studied in order to verify if they are suitable for use as TL dosimeter. The dose response that was analyzed cover the wide dose range 0.34-5.44 kGy. The measured glow curves show complex structures which were evaluated with kinetic parameters based on the MO (Mix Order) model together with the CGCD (Computerized Glow Curve Deconvolution) homemade program which is useful to understand the mechanisms responsible for TL emission.

In the current work, it has been presented TL model, which includes one trap three recombination centers. Simulation of the model followed the stages of irradiation, relaxation, and heating. The appropriate set of coupled differential equations has been developed for each stage. Numerical solving of those equations in sequence it has been demonstrated that, with appropriate choices of the sets of trapping parameters, three TL peaks occur related to three recombination centers. Thus, we can conclude that they would have different emission spectra.

As thallium (Tl) is a highly toxic heavy metal, there are compulsory environmental regulations in many countries on minimizing its release. This research investigated the treatment of real industrial wastewater with low Tl(I) concentration by Fe0-electrocoagulation (Fe0-EC) in a batch aeration-forced pump cycle reactor. The effects of pH (7–12), current density (8.3–33.3 mA/cm2), dissolved oxygen (DO) in wastewater, and initial Tl(I) concentration (66–165 µg/L) on Tl(I) removal efficiency were investigated. The removal efficiency of Tl(I) is pH-dependent, to be exact, it increases significantl
