Thermally modulated optically stimulated luminescence (TM-OSL) of quartz

Journal of Luminescence, 2018
Abstract It has recently been shown in computer simulations of the OSL process that increasing the temperature during optical stimulation allows the probability of electron excitation from traps to the conduction band to be modulated. This, in turn, facilitates the efficient separation of individual OSL components. A result of the thermally modulated

Development of new optically stimulated luminescence (OSL) neutron dosimeters

Radiation Measurements, 2008
Abstract This paper demonstrates the possibility of using neutron converters incorporated into Al 2 O 3 : C dosimeters to produce new neutron-sensitive OSL dosimeters suitable for personal monitoring. A comparison between different neutron converters indicate that lithium-based compounds (6LiF and Li 2 6 ...

A two-stage thermally-assisted optically stimulated luminescence (TA-OSL)

International Journal of Science and Research Archive, 2022
A two-stage thermally-assisted optically stimulated luminescence model is studied. Electrons are thermally and optically raised from the ground state to an excited state and there after they are thermally raised from the excited state to the conduction band.

An alternative technique for optically stimulated luminescence (OSL) experiment

Radiation Measurements, 1996
An alternative technique is developed for observation of OSL by linearly increasing the intensity of the excitation source during readout. The technique allows the observation of OSL signals in the form of peaks unlike the decaying curves. The parameters of the new OSL peak can be used to obtain the intensity and the lifetime of the decay.

Application of the optically stimulated luminescence (OSL) technique in space dosimetry

Radiation Measurements, 2006
Abstract This paper reviews the state of the optically stimulated luminescence (OSL) technique for space dosimetry applications, focusing on the properties of carbon-doped aluminum oxide (Al 2 O 3 :C). New data presented include the most complete and recent values for the relative efficiency η HCP , γ for heavy charged particles as a ...

Independent evaluation of optically stimulated luminescence (OSL) 'dot' dosemeters for environmental monitoring

Radiation Protection Dosimetry, 2010
Optically stimulated luminescence (OSL) 'dot' dosemeters (manufactured by Landauer®) are reported to have a high degree of environmental stability, high level of sensitivity and provide wide range of dose measuring capabilities from 0.05 mGy to 100 Gy.

Application of the optically stimulated luminescence (OSL) technique for mouse dosimetry in micro‐CT imaging

Medical Physics, 2013
Purpose:Micro‐CT is considered to be a powerful tool to investigate various models of disease on anesthetized animals. In longitudinal studies, the radiation dose delivered by the micro‐CT to the same animal is a major concern as it could potentially induce spurious effects in experimental results.

Optically stimulated luminescence (OSL) of LiMgPO 4 :Tm,Tb phosphor

Journal of Rare Earths, 2017
Abstract LiMgPO 4 :Tm,Tb phosphors were synthesized using a solid-state diffusion method. Their properties were investigated using X-ray diffraction (XRD), thermoluminescence (TL), scanning electron microscopy (SEM), and OSL dosimetric techniques. The influence of light stimulation and thermal excitation on the TL and OSL, and the reusability of the ...

A laboratory inter-comparison of quartz optically stimulated luminescence (OSL) results

Quaternary Science Reviews, 1997
Abstract In this study three sediment samples were used which came from two cave sites situated on the coast of Gibraltar, Gorham's Cave and Vanguard Cave. Both caves contain silts, sands and breccia deposits from the last interglacial through to the post-glacial period, from which beach sands were sampled for dating.

Review of optically stimulated luminescence (OSL) instrumental developments for retrospective dosimetry

Radiation Measurements, 2010
This review describes 40 years of experience gained at Riso National Laboratory in the development of facilities for irradiation, thermal/optical stimulation and luminescence signal detection. These facilities have mainly been used in luminescence dating and nuclear accident dosimetry.
