Thermoluminescence and optically stimulated luminescence properties of natural barytes

Applied Radiation and Isotopes, 2010
Heavy, baryte-loaded, concrete is commonly used as radiation shielding material around high energy particle accelerators. Concrete samples received from a shielding block located at CERN cite contain many crystalline inclusions which were identified as barytes by X-ray diffraction analysis and separated by their color, classified as white, orange and ...

Thermoluminescence and optically stimulated luminescence of gamma-irradiated mineral zircon [PDF]

, 2007
Thermoluminescence (TL) manifested by gamma-irradiated mineral zircon has shown a strong TL peak at about 165 °C which is due to recombination of electrons and Dy3+ related shallow hole traps.

Investigation into main luminescence properties of various natural salt samples using TL and OSL tecniques

Фізика і хімія твердого тіла
In this study, the natural salt minerals of Turkey were investigated using Thermoluminescence (TL) and optically stimulated luminescence (OSL). For this purpose, luminescence dosimetric properties such as glow curve shape, fading, dose-response ratio ...

La datation du Paléolithique moyen et ancien par OSL. Apports et nouveautés à travers l’exemple du site de Romentères

Archéopages, 2010
The method known as OSL dating, or Optically Stimulated Luminescence, can be applied to any commonly found mineral exposed to daylight before it was buried and allows us to date any sedimentary deposit containing such minerals.

Integrated chronological control on an archaeologically significant Pleistocene river terrace sequence: the Thames-Medway, eastern Essex, England [PDF]

, 2012
Late Middle Pleistocene Thames-Medway deposits in eastern Essex comprise both large expanses of Palaeolithic artefact-bearing river sands/gravels and deep channels infilled with thick sequences of fossiliferous fine-grained estuarine sediments that yield

Thermo-optical properties of optically stimulated luminescence in feldspars

, 1994
Optically stimulated luminescence processes in feldspars are subject to competing thermal enhancement and quenching processes: this article describes the thermal enhancement effects for orthoclase, albite and plagioclase feldspars.

Analyzing gamma irradiated Spectrolite in relation to the photo-transfer TL and OSL effects

Brazilian Journal of Radiation Sciences
Thermoluminescence (TL) and optically stimulated luminescence (OSL) are two techniques based in the luminescence phenomenon. They can be applied to study the response of materials which present the property of emitting light after the steps of ...

Influence of crystal structure on the optically stimulated luminescence properties of feldspars

, 1994
Work is presented showing that the crystal structure of feldspar plays an important role in determining the energy positions at which optically stimulated luminescence transitions can occur, their thermo-optical behavior, the transport properties of ...
