An alternative technique for optically stimulated luminescence (OSL) experiment
Radiation Measurements, 1996An alternative technique is developed for observation of OSL by linearly increasing the intensity of the excitation source during readout. The technique allows the observation of OSL signals in the form of peaks unlike the decaying curves. The parameters of the new OSL peak can be used to obtain the intensity and the lifetime of the decay.

This review describes 40 years of experience gained at Riso National Laboratory in the development of facilities for irradiation, thermal/optical stimulation and luminescence signal detection. These facilities have mainly been used in luminescence dating and nuclear accident dosimetry.

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.

Application of the optically stimulated luminescence (OSL) technique in space dosimetry
Radiation Measurements, 2006Abstract This paper reviews the state of the optically stimulated luminescence (OSL) technique for space dosimetry applications, focusing on the properties of carbon-doped aluminum oxide (Al 2 O 3 :C). New data presented include the most complete and recent values for the relative efficiency η HCP , γ for heavy charged particles as a ...

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
