Thermo luminescence in two varieties of jadeite: Irradiation effects and application to high dose dosimetry
(Elsevier B.V., 2014-12-01)
The thermoluminescence properties of white (WJ) and green (GJ) mineral jadeite have been investigated with a view to be of use in high dose dosimetry. WJ presented glow curve with 110,190 and 235 degrees C peaks. All these ...
Synthesis, thermoluminescence, defect center and dosimetric characteristics of LiF:Mg,Cu,P,Si phosphor
(Pergamon-Elsevier Science Ltd, 2017)
LiF:Mg,Cu,P,Si (MCPS), a new tissue equivalent phosphor, was synthesized by solid state method. Powder x-ray diffraction and scanning electron microscope were employed to determine the structural features. The dosimetric ...
Centers responsible for the TL peaks of willemite mineral estimated by EPR analysis
(Elsevier Science Bv, 2016)
The mineral willemite (Zn2SiO4) exhibits five thermoluminescence (TL) peaks approximately at 160, 225, 260, 310 and 400 degrees C. Electron paramagnetic resonance (EPR) studies were carried out to study the defect centers ...
Dating and determination of firing temperature of ancient potteries from São Paulo II archaeological site, Brazil by TL and EPR techniques
(Elsevier B.V., 2015-05-01)
Pottery fragments from São Paulo II (SPII) archaeological site were dated by means of thermoluminescence (TL) and electron paramagnetic resonance (EPR). EPR was used to study the firing temperature using the iron signal ...
Thermoluminescence in Lapis Lazuli crystal: Glow peaks and their connection with F-centers estimated by ESR analysis
(Elsevier Science Bv, 2017)
The mineral Lapis Lazuli exhibits three thermoluminescence (TL) peaks approximately at 140, 260 and 370 degrees C. The TL intensity of the three peaks grows with radiation dose and it saturates only beyond 9 kGy. Electron ...
Thermoluminescence and optical absorption properties of glass from natural diopside and of synthetic diopside glass
(Elsevier Science Bv, 2017)
Glasses based on natural mineral diopside and synthetic glasses starting from Oxides of magnesium, calcium and silicon, and some of these glasses doped with 0.1, 1.0, 2.0 and 4.0% of Ag, have been produced for the study ...
OSL and EPR dating of pottery from the archaeological sites in Amazon Valley, Brazil
(Elsevier B.V., 2014-11-26)
Pottery fragments from the Hatahara archaeological site, Amazon Valley, have been dated by thermoluminescence (TL), optically stimulated luminescence (OSL) and electron paramagnetic resonance (EPR) techniques. X-ray ...
Studies of Radiation-Induced Defects in Li2SiO3:Sm Phosphor Material
(Springer, 2017)
Li2SiO3:Sm was synthesized by the solution combustion method. Powder x-ray diffraction technique was used to find the phase formation. Li2SiO3:Sm exhibits thermoluminescence (TL) peaks at approximately 140 degrees C, 155 ...
Effects of high-temperature annealing on ESR properties of solid solutions of garnet minerals
(Pergamon-Elsevier Science Ltd, 2016)
A garnet (G7) silicate mineral belonging to pyralspite subgroup was studied using the technique of electron spin resonance (ESR). This study shows that iron is present in G7 as isolated species as well as species coupled ...
High- and very-high-dose dosimetry using silicate minerals
(Elsevier B.V., 2015-01-01)
In the present study, certain natural silicate minerals such as aquamarine (AB), morganite (PB), goshenite (WB), white jadeite (JW), green jadeite (JG), pink tourmaline (PT) and two varieties of jadeite-like quartz, denoted ...
