Optically stimulated luminescence of Al2O3

Radiation Measurements, 1998
Abstract Anion-deficient aluminum oxide doped with carbon (Al 2 O 3 :C) is not only an extremely sensitive thermoluminescence (TL) material, but is well suited to optically stimulated luminescence OSL applications due to a high cross-section for interaction of light with radiation-induced trapped charge.

Optically Stimulated Luminescence Dosimetry

Radiation Protection Dosimetry, 1983
Abstract Optically stimulated luminescence from MgS:Eu,Sm phosphors is characterised. First analysis shows that this method has some interesting features for dosimetry measurments: high sensitivity, non heating and fast reading time can be retained. Widespread use of this technique will require some complementary investigations.

Optically Stimulated Luminescent Glass Optical Fibre Dosemeter

Radiation Protection Dosimetry, 2002
An optical fibre radiation dosemeter has been developed that utilises optically stimulated luminescence and scintillation to provide independent, remote, real-time dose measurements. The radiation sensitive element consists of a 1 mm long, 0.4 mm diameter piece of copper-ion-doped fused quartz that is attached to a 1 m length of commercial optical ...

Optically and thermally stimulated luminescence characteristics of MgO:Tb3+

Radiation Protection Dosimetry, 2006
In this paper main optically stimulated luminescence (OSL) and thermoluminescence (TL) characteristics are presented of a newly synthesised material MgO doped with terbium (Tb) developed at the Institute of Nuclear Science, Vinca. A thermally stimulated emission spectrum showed the characteristic lines of Tb3+ in a wide range of wavelengths.

Radiation Dosimetry by Optically-stimulated Luminescence of BeO

Health Physics, 1970
Abstract A radiation dosimeter utilizing the optically-stimulated luminescence of BeO permits repeated readings on a single sample. The response as a function of exposure is supralinear and saturates at 3 × 105 R. The lower useable limit is determined by an inherent background signal. The lower limit for BeO powder is 1 R and for BeO disks is 10 R.

Ionic mechanisms in the optically stimulated luminescence of quartz

physica status solidi c, 2007
AbstractAmong 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, 2000
Optically 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, 2006
The 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.
