Technical note: Darkroom lighting for luminescence dating laboratory [PDF]
Geochronology, 2023 An optimal lighting setting for the darkroom laboratory is fundamental for the accuracy of luminescence dating results. Here, we present the lighting setting implemented in the new Luminescence Dating Research Laboratory at Stony Brook University, USA ...

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 ...

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.

Journal of Medical Radiation Sciences, EarlyView.This study examined how well radiographers in five major Namibian state hospitals understand and use Personal Radiation Monitoring Devices (PRMD), a critical tool for occupational safety. While most respondents showed strong knowledge and awareness of PRMDs, many were unaware of their own radiation exposure and rarely reviewed their dose records ...

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

Journal of the Royal Anthropological Institute, EarlyView.Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.
