Optically stimulated luminescence (OSL) of Lu2SiO5:Ce powder: A preliminary study
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2011Abstract Optically stimulated luminescence (OSL) of Lu2SiO5:Ce powder (Phosphor Technology Ltd., UK) has been measured by Riso TL/OSL Reader (TL-DA-15). Upon blue photon stimulation (λex ∼470 nm) the material shows strong OSL signal that can detect β-irradiation right up to the dose of ∼0.2 Gy.

A laboratory inter-comparison of quartz optically stimulated luminescence (OSL) results
Quaternary Science Reviews, 1997Abstract In this study three sediment samples were used which came from two cave sites situated on the coast of Gibraltar, Gorham's Cave and Vanguard Cave. Both caves contain silts, sands and breccia deposits from the last interglacial through to the post-glacial period, from which beach sands were sampled for dating.

Abstract Recently it was shown that making use of the dependency of optical cross-section (OCS) of trap on the experimental parameters can help to enhance the ability to separate signals from different traps. When the light source applied for stimulation delivers the spectral band of a finite width, the physical quantity that governs the luminescence

Optically stimulated luminescence (OSL) images of some X- and γ-irradiated granite slices were obtained using photon detection through a 570 nm bandpass filter with diode-laser excitation of 910 nm. Alternative photo-induced phosphorescence (PIP) images, which were colour photographed immediately after the sunlight exposure of slice samples, were also ...

Abstract A new method of OSL stimulation using the continuous increase of stimulation energy (VES-OSL) has been previously suggested. Earlier computer simulations showed that this type of stimulation results in a peak-shaped OSL curve that closely resembles the TL peak. VES-OSL measurements were performed using a stimulation source that was specially
