Slow OSL component in quartz separated by TM-OSL method

Radiation Measurements, 2020
Abstract The thermal stability of the slow component measured by the thermally modulated optically stimulated luminescence (TM-OSL) method was investigated for quartz from geological sediments. The TM-OSL stimulation was carried out with the stimulation wavelength of 470 nm and the heating rate of 2 Ks−1 after the effective bleaching of the faster ...

OSL properties of KMgF3:Tm3+ for dosimetric applications as OSL dosimeter

Applied Radiation and Isotopes, 2018
The optically stimulated luminescence (OSL) properties of undoped and Tm3+-doped KMgF3 fluoroperovskite have been investigated for the first time. KMgF3 compounds were synthesized by solid state reaction method and two different procedures were employed to improve the contact among the reagents, namely, the compressed powder was put either in an ...

Intercomparison study of sensitivities from commercial OSL readers and a newly developed OSL reader

Radiation Protection Dosimetry, 2023
Abstract In this study, we compared the sensitivities of a newly designed OSL system with two commercial systems, performing OSL readouts of Al2O3:C irradiated with doses ranging from mGy to a few Gy. It is our first prototype, and we used a cluster of three blue LEDs (5 W each and approximately wavelength 450 nm) for the optical ...

Thermally modulated OSL related to the fast component of the OSL signal in quartz

Radiation Measurements, 2018
Abstract The methods of optically stimulated luminescence (OSL) measurements used until recently applied optical stimulation at a constant temperature, with a constant stimulation energy and a constant or linearly increased flux of stimulation photons. During such stimulation the optical cross-section of traps is invariable and it is hard to separate

Different components of the quartz OSL signal resolved by the TM-OSL method

Radiation Measurements, 2019
Abstract Recently it has been shown that the thermally modulated optically stimulated luminescence (TMOSL) method, which is based on optical stimulation during linear heating of the sample, can be used successfully to extract the individual OSL components during the experimental stage. Such a possibility is important in OSL dating of sediments, where

New light on OSL

Quaternary Science Reviews, 1999
Abstract We have tested recently released green and blue light emitting diodes (LEDs) for the optical stimulation of quartz, with a view to using these in routine optically stimulated luminescence (OSL) dating and retrospective dosimetry. We compare results obtained with blue LEDs with those obtained using broad-band blue/green light filtered from a ...

OSL dosimeters for dental panoramic radiography

Applied Radiation and Isotopes, 2018
The aim of the present work is to determine dosimetric characteristics of commercial optically stimulated luminescence dosimeter (OSLD) to estimate equivalent dose in the patient undergoing panoramic radiography procedure. Digital panoramic unit "Instrumentarium OP200D" was used.
