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.

Radiation-induced growth and isothermal decay of infrared-stimulated luminescence from feldspar [PDF]

, 2015
Optically stimulated luminescence (OSL) ages can determine a wide range of geological events or processes, such as the timing of sediment deposition, the exposure duration of a rock surface, or the cooling rate of bedrock.

Optically stimulated luminescence dosimetry on mobile phone back protective glass

Physics Open, 2021
Protective glasses from the back of modern smartphones were tested as potential emergency dosimeters using optically stimulated luminescence (OSL). The glasses were shown to exhibit several favorable dosimetric properties including a strong sensitivity ...

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

Differential bleaching of quartz and feldspar luminescence signals under high-turbidity conditions [PDF]

Geochronology, 2023
Sediment burial dating using optically stimulated luminescence (OSL) is a well-established tool in geochronology. An important but often inapplicable requirement for its successful use is that the OSL signal is sufficiently reset prior to deposition ...

Luminescence characteristics of muddy sediments in the turbidity maximum zone of the Yangtze River mouth and implications for the depositional mechanisms

Frontiers in Earth Science, 2022
Muddy sediments are the most prominent constituents of sedimentary successions in tide-dominated river deltas and have highly complex depositional mechanisms.

Anomalous luminescence of subglacial sediment at Haut glacier d'Arolla, Switzerland - a consequence of resetting at the glacier bed? [PDF]

, 2010
<p>Luminescence has the potential to elucidate glacial geomorphic processes because primary glacial sediment sources and transport pathways are associated with contrasting degrees of exposure to light.

Sintering sodium chloride crystals for applications in optically stimulated luminescence (OSL) dosimetry

Brazilian Journal of Radiation Sciences, 2022
The main objective of this work was to study a new technique for the sintering of marine sodium chloride (NaCl) crystals obtained from seawater. In order to obtain an efficient luminescence, a better control in the amount of sample to be used, a better ...
