EPJ Web of Conferences, 2018 Single photon detection applied to optically stimulated luminescence (OSL) dosimetry is a promising approach due to the low level of luminescence light and the known statistical behavior of single photon events.

The problem of dating quartz 1 : Spectroscopic ionoluminescence of dose dependence
, 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 ...

Optically stimulated luminescence dating reveals rate of beach ridge and sand spit depositions from the upper Gulf of Thailand [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2019 This study aimed to increase the understanding of the history of late Quaternary coastal evolution. An analysis was carried out on the optically stimulated luminescence (OSL) dates of 12 quartz-rich samples collected from the Chanthaburi paleosand spit ...

A review of the optically and thermally stimulated luminescence properties of aluminosilicates
Optical Materials: XThis paper reviews the main literature describing models for thermoluminescence (TL), optically stimulated luminescence (OSL) and radiophotoluminescence (RPL) in aluminosilicate materials, namely natural feldspar minerals and synthetic glasses.

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

Optically Stimulated Luminescence (OSL) Dating of Shallow Marine Sediments
The Quaternary Research (Daiyonki-Kenkyu), 2003 段丘堆積物の年代測定研究の一環として,光ルミネッセンス(OSL)年代測定法の浅海成堆積物への適用性を検討した.まず,石英の光曝・加熱・エッチング実験を実施し,この結果に基づく試料調整手順を示した.続いて,年代既知(酸素同位体ステージ5e～5c)の浅海成堆積物を対象として,付加線量法によるOSL年代測定を実施した.この結果,前浜堆積物および前浜～外浜遷移帯堆積物から,層位学的・地形学的に推定される離水年代とおおむね調和的な88～112kaのOSL年代値を得た.一方,後浜堆積物ではより新しく,外浜堆積物ではより古いOSL年代値が得られた.これらの結果から,前浜堆積物および前浜～外浜遷移帯堆積物中では光ブリーチングが成立していると考えられる.したがって,精度は粗いが ...
