Different components of the quartz OSL signal resolved by the TM-OSL method

Radiation Measurements, 2019
Abstract Recently it has been shown that the thermally modulated optically stimulated luminescence (TMOSL) method, which is based on optical stimulation during linear heating of the sample, can be used successfully to extract the individual OSL components during the experimental stage. Such a possibility is important in OSL dating of sediments, where

Optically stimulated luminescence (OSL) and thermally assisted OSL in Eu2+ – Doped BaSO4 phosphor

Radiation Measurements, 2014
Abstract BaSO4:Eu2+ phosphor has been investigated for its photoluminescence (PL), thermoluminescence (TL), TL kinetics, optically stimulated luminescence (OSL) and thermally assisted OSL (TA-OSL) response. PL spectra showed the characteristic emission of Eu2+ ion at 375 nm when excited by 320 nm. The luminescence lifetime has been measured as 40 and

Minimizing feldspar OSL contamination in quartz UV-OSL using pulsed blue stimulation

Radiation Measurements, 2008
Natural sediments usually contain a mix of quartz and feldspar. Because these two minerals have different luminescence properties and record different natural doses it is normally necessary to physically separate them before measurement. This paper investigates the potential of using pulsed stimulation to separate the optically stimulated luminescence ...

Multi-OSL-thermochronometry of feldspar

Quaternary Geochronology, 2016
Abstract Optically stimulated luminescence (OSL)-thermochronometry has recently been proposed as a tool capable of resolving cooling histories from the top 1–2 km of the Earth's crust. This is beyond the resolution of most low-temperature thermochronometric systems, and it offers a new opportunity to investigate the interactions between climate ...

Thermally assisted OSL (TA-OSL) from various luminescence phosphors; an overview

Radiation Measurements, 2016
Abstract The current status of the results on the thermally assisted optically stimulated luminescence (TA-OSL) signal performed on various naturally occurring as well as artificial luminescent phosphors is described. TA-OSL of anion deficient alumina doped with carbon and quartz has been reported to be effectively used towards dosimetry purposes ...

Time-Resolved OSL Experiments

2020
In this chapter we discuss experimental data and models for time-resolved optically and infrared stimulated luminescence (TR-OSL, TR-IRSL).These techniques can help researchers understand the luminescence mechanisms involved in dosimetric materials. We show how to use R in order to extract the luminescence lifetimes from TR experimental data and show ...
