Optically stimulated luminescence (OSL) as a chronometer for surface exposure dating [PDF]

Journal of Geophysical Research: Solid Earth, 2012
We pioneer a technique of surface‐exposure dating based upon the characteristic form of an optically stimulated luminescence (OSL) bleaching profile beneath a rock surface; this evolves as a function of depth and time. As a field illustration of this new method, the maximum age of a premier example of Barrier Canyon Style (BCS) rock art in Canyonlands ...

Optically stimulated luminescence (OSL) dosimetry in irradiated alumina substrates from mobile phone resistors [PDF]

Radiation and Environmental Biophysics, 2017
In this study the dosimetric properties of alumina (Al2O3) substrates found in resistors retrieved from mobile phones were investigated. Measurements of the decline of optically stimulated luminescence (OSL) generated following exposure of these substrates to ionising radiation showed that 16% of the signal could still be detected after 2 years (735 ...

Optically Stimulated Nanodosimeters with High Storage Capacity [PDF]

Nanomaterials, 2019
In this work we report on the thermoluminescence (TL) and optically stimulated luminescence (OSL) properties of β-Na(Gd,Lu)F4:Tb3+ nanophosphors prepared via a standard high-temperature coprecipitation route.

Optically stimulated luminescence (OSL) from Ag-doped Li2B4O7 crystals [PDF]

Journal of Luminescence, 2016
Abstract Optically stimulated luminescence (CW-OSL) is observed from Ag-doped lithium tetraborate (Li 2 B 4 O 7 ) crystals. Photoluminescence, optical absorption, and electron paramagnetic resonance (EPR) are used to identify the defects participating in the OSL process. As-grown crystals have Ag + ions substituting for Li + ions. They also have Ag

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.

The role of heat treatment in improving photoluminescence and optically stimulated luminescence of HfO2 [PDF]

EPJ Web of Conferences, 2022
HfO2 is a metal oxide from the IV-B family whose properties have been widely applied in electronics and which displays an important blue emission. Despite this fact, few studies have been dedicated to understanding the role of heat treatment on its ...

Towards an improvement of optically stimulated luminescence (OSL) age uncertainties: modelling OSL ages with systematic errors, stratigraphic constraints and radiocarbon ages using the R package BayLum

, 2021
. Statistical analysis has become increasingly important in optically stimulated luminescence (OSL) dating since it has become possible to measure signals at the single-grain scale.

Proposing a new conceptual model for the reconstruction of ice dynamics in the SW sector of the Scandinavian Ice Sheet (SIS) based on the reinterpretation of published data and new evidence from optically stimulated luminescence (OSL) dating

E&G Quaternary Science Journal, 2020
. We propose a new concept of the Weichselian ice dynamics in the south-western sector of the Baltic Sea depression. The review of existing geochronological data from Germany, Denmark and southernmost Sweden in combination with new optically stimulated ...
