Thermoluminescence responses of terbium-doped magnesium orthosilicate with different synthesis conditions.
Numerous materials have been proposed for thermoluminescence dosemeter, and the example of highest sensitivity is cited as magnesium orthosilicate doped with terbium (Mg2SiO4:Tb). Nevertheless, the material is currently not commercially attractive because the sensitivity varies greatly with synthesis techniques. This is a multi-parameter problem, and the current work explores some of the condit...
متن کاملIon size effects on thermoluminescence of terbium and europium doped magnesium orthosilicate
Thermoluminescence (TL) and radioluminescence (RL) are reported over the temperature range 25–673 K from MgSiO4:Tb and MgSiO4:Eu. The dominant signals arise from the transitions within the Rare Earth (RE) dopants, with limited intensity from intrinsic or host defect sites. The Tb and Eu ions distort the lattice and alter the stability of the TL sites and the peak TL temperature scales with the ...
متن کاملThermoluminescence characteristics and kinetic analysis of copper doped magnesium sulfate in gamma irradiation
MgSO4:Cu phosphor was synthesized by solid state method. Optimum concentration of copper was determined at 0.1 mol%. Thermoluminescence characteristics of MgSO4:Cu was studied following gamma irradiation. A linear dose response was observed in dose range of 1Gy to 500Gy. Reusability of this sample was tested after 10 cycles of gamma irradiation and it revealed that the intensity remains approxi...
متن کاملThermoluminescence characteristics of Ge-doped optical fibers with different dimensions for radiation dosimetry.
Important thermoluminescence (TL) properties of five (5) different core sizes Ge-doped optical fibers have been studied to develop new TL material with better response. These are drawn from same preform applying different speed and tension during drawing phase to produce Ge-doped optical fibers with five (5) different core sizes. The results of the investigations are also compared with most com...
متن کاملThermoluminescence kinetic parameters of different amount La-doped ZnB₂O₄.
The kinetic parameters of 1%, 2%, 3% and 4% La-doped ZnB2O4 phosphors (i.e. ZnB2O4:0.01La, ZnB2O4:0.02La, ZnB2O4:0.03La and ZnB2O4:0.04La) synthesized by nitric acid method have been calculated. Thermoluminescence (TL) glow curves of ZnB2O4:La phosphors after beta-irradiation showed a very well defined main peak having the maximum temperature at around 200°C and a shoulder peak at around 315°C ...
