Ionic mechanisms in the optically stimulated luminescence of quartz
physica status solidi c, 2007AbstractAmong the many centres found in crystalline quartz it is well known that Al, substitutional for Si, is always present in different concentrations giving rise at Room Temperature to ionic migration of the associated alkali ions. Many authors evidenced that these alkali ions are involved in trapping and recombination at the basis of Thermally and

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 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.

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.

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: A brief overview
Radiation Measurements, 2011The use of optically stimulated luminescence (OSL) in radiation dosimetry has been conditioned by the availability of suitable dosimetry (OSLD) materials. The crucial property dictating the suitability of a material as an OSLD is the material’s defect structure.

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.
