Dose-Response Behavior of Dental Material Using General Kinetic Order and Lambert W Deconvolution Models in CW-OSL [PDF]

open access: yesMethods and Protocols
The present study presents a comparative evaluation of two analytical deconvolution models applied to Optically Stimulated Luminescence (OSL) decay curves of zirconia-reinforced lithium silicate (ZLS), a glass-ceramic material with potential applications

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

open access: yesRadiat Environ Biophys, 2018
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]

open access: yesNanomaterials, 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) of dental enamel for retrospective assessment of radiation exposure. [PDF]

open access: yesRadiat Meas, 2007
This paper briefly reviews the optically stimulated luminescence (OSL) properties of dental enamel and discusses the potential and challenges of OSL for filling the technology gap in biodosimetry required for medical triage following a radiological/nuclear accident or terrorist event.

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

open access: yesEPJ 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 ...

Lithic Miniaturization Provides a Signature of an MIS4-3 Southern Dispersal of Homo sapiens. [PDF]

open access: yesEvol Anthropol
ABSTRACT Fossil and artefactual evidence shows Homo sapiens in Eurasia well before 75 ka. However, genetic evidence suggests all extant non‐African populations derive almost all of their ancestry from a dispersal that only diverged in the last 60–50 ka. In northern Eurasia, the Upper Paleolithic with its laminar blade knapping provides an archeological

Thermoluminescence and optically stimulated luminescence studies of Indian soils for its application in retrospective dosimetry

open access: yesRadiation Protection and Environment, 2021
Optically stimulated luminescence (OSL) of quartz obtained from ceramics, concrete, and soil has been studied extensively for its use in retrospective dosimetry.

Luminescence Dating of Rock Surface. The Case of Monoliths from the Megalithic Sanctuary of Ossimo-Pat (Valle Camonica, Italy)

open access: yesApplied Sciences, 2020
Ossimo-Pat megalithic sanctuary (Valle Camonica, BS, Italy) is one of the most relevant archaeological findings of the southern alpine region, for the variety of its structures and the quality of its engraved monoliths.
