Optically stimulated luminescence of alexandrite
Optical Materials: XWe report the optically stimulated luminescence (OSL) of natural alexandrite (BeAl2O4:Cr3+) from Brazil. Luminescence was stimulated using 470 nm blue, 525 nm green and 850 nm infrared light.

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 ...

Thermally Assisted Optically Stimulated Luminescence (TA-OSL) from Commercial BeO Dosimeters
Materials, 2023 BeO is another luminescent phosphor with very deep traps (VDTs) in its matrix that could not be stimulated using either thermal or conventional optical stimulations. The present study attempts to stimulate these traps using thermally assisted optically stimulated luminescence (TA-OSL), a combination of simultaneous thermal and optical stimulation that ...

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 ...
