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 stimulated luminescence in enaminones

Radiation Physics and Chemistry, 2020
Abstract This work presents the first experimental results of optically stimulated luminescence in organic crystals type enaminones. Samples were synthesized by means of the condensation reaction of acetylacetone with four aromatics amines in acid medium.

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 luminescence of persistent luminescence materials

Journal of Luminescence, 2006
Abstract For around ten years, intense attention has been devoted to materials which exhibit strong persistent luminescence. The Eu 2+ doped SrAl 2 O 4 is probably the best one. Co-doping with other trivalent rare earth ions, especially with Dy 3+ , enhances the persistent luminescence.

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

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2001
Abstract 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 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

Frequency modulated pulsed stimulation in optically stimulated luminescence

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2001
Abstract A new pulsed-OSL stimulation unit capable of producing stimulation pulses down to 4 μs wide has been developed. A matrix of 49 light emitting diodes (LEDs) are pulsed using a voltage-to-frequency converter, which produces fixed width pulses of adjustable duty cycle in the frequency range 0–10 kHz.

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.
