Optically stimulated luminescence dating of sediments
AIP Conference Proceedings, 2000Optically stimulated luminescence (OSL) dating methodology was applied on the coarse grain fraction (100÷500 μm thick) of quartz crystals (green light stimulated luminescence, GLSL) and feldspar crystals (infrared stimulated luminescence, IRSL) taken from sections at different depths of cores bored in various coastal lagoons (Longarini, Cuba, Bruno) in

Modelling of optically stimulated luminescence of zircon: assessment of the suitability for dating
Journal of Physics D: Applied Physics, 2006The mineral zircon, ZrSiO4, is a candidate material for optical dating because it exhibits luminescence after exposure to natural radioactivity. The kinetic model of zircon thermally stimulated luminescence proposed before has been modified and used to investigate optically Stimulated luminescence (OSL) of zircon.

Optically stimulated luminescence in NaMgF3:Eu2+
Applied Physics Letters, 2007Optically stimulated luminescence (OSL) and thermoluminescence (TL) measurements were performed on polycrystalline NaMgF3:Eu2+ as well as sintered and quenched NaMgF3:Eu2+ after exposure to ionizing radiation. The authors find a range of TL traps and the sintering and quenching process reduces the concentration of shallow traps.

Optically stimulated luminescence dosimetry
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2001Abstract Models and the conceptual framework necessary for an understanding of optically stimulated luminescence (OSL) are described. Examples of various OSL readout schemes are described, along with examples of the use of OSL in radiation dosimetry.

Recent development in the optical stimulation of luminescence
Radiation Measurements, 2017Abstract Both in thermoluminescence (TL) and in optically stimulated luminescence (OSL), the physical quantity that governs the luminescence process is the probability of electron release from a trap. Thanks to the usage of the temperature dependence of this quantity, the TL analysis enables estimation of the parameters that determine uniquely a trap.

Optically stimulated luminescence in synthetic quartz
Journal of Luminescence, 1994Abstract Optically stimulated luminescence (OSL), has been studied in synthetic quartz crystals, which had previously been exposed to β- or X-irradiations. The main emission bands appeared at ≈380 and ≈440 nm. The excitation spectra of these emission bands were now measured and showed both a maximum at 330 nm.

Optically Stimulated Luminescence Dosimetry: An Introduction
Solid State Phenomena, 2015A subset of solid state materials have long been used as integrating dosimeters because they store energy deposited as a result of their interactions with ionizing radiation and then, when stimulated appropriately, release a proportionate amount of visible or near-visible light.

Peculiarities of optically stimulated luminescence in halite
Radiation Measurements, 2016Abstract Sodium chloride – NaCl is one of materials indicating strong OSL signal after exposure on ionizing radiation. Previous studies of the OSL response in pure sodium chloride showed coexistence of fading and regeneration of the signal using the newly developed variable delay optically stimulated luminescence technique (VD-OSL).
