Optically stimulated luminescence of alexandrite

open access: yesOptical Materials: X
We report the optically stimulated luminescence (OSL) of natural alexandrite (BeAl2O4:Cr3+) from Brazil. Luminescence was stimulated using 470 nm blue, 525 nm green and 850 nm infrared light.

Impact of X-ray beam quality on organ-absorbed dose in chest CT: Evaluation using spectral analysis and beam-shaping filters. [PDF]

open access: yesJ Appl Clin Med Phys
Abstract Background In computed tomography (CT), radiation dose is commonly evaluated using system‐displayed metrics such as CTDIvol; however, variations in X‐ray beam quality may influence organ absorbed dose even under identical CTDIvol conditions.

On the analysis of photon arrival time distributions obtained using the pulsed optically stimulated luminescence technique [PDF]

open access: yes, 2022
The objective of this work is to address the analysis of photon arrival time distributions (PATDs) obtained using the pulsed optically stimulated luminescence (POSL) technique in two particular situations: (a) when the interval between pulses is ...

Mid- to Late-Quaternary evolution of the Wilderness Barrier dunes, South Africa [PDF]

open access: yes, 2011
Barrier dunes represent potentially long-term, but complex, archives of coastal evolution. The examples occupying the Wilderness embayment, on the southern Cape coast of South Africa, form a regionally unique system of three shore-parallel barriers ...

The problem of dating quartz 1 : Spectroscopic ionoluminescence of dose dependence [PDF]

open access: yes, 2010
This work is partially supported by NERC studentship F008589/1.A suite of quartz samples of different provenances, irradiation, thermal and depositional histories were analysed using spectroscopic ionoluminescence (IL) to investigate variations in ...

Dating stone arrangements using optically stimulated luminescence and fallout radionuclides

open access: yes, 2022
Buildings and monuments constructed from stone provide some of the best-preserved surface archaeology, but their construction ages can be difficult to determine using radiocarbon techniques.

Thermally assisted IRSL and VSL measurements of display glass from mobile phones for retrospective dosimetry

open access: yesNuclear Engineering and Technology, 2022
Investigations of retrospective dosimetry have shown that components of mobile phones are suitable as emergency dosimeters in case of radiological incidents. For physical dosimetry, components can be read out using optically stimulated luminescence (OSL),

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

open access: yes, 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

Study of optically stimulated luminescence in K2SO4:Ce

open access: yesRadiation Protection and Environment, 2018
Highly sensitive cerium-doped K2SO4phosphor was synthesized for optically stimulated luminescence (OSL) properties. The present study mainly investigated various kinetic parameters and correlation between the thermoluminescence and OSL (TL-OSL) processes.
