Preparation, kinetic analysis and thermoluminescent dosimetry features of highly sensitive SrF2:Dy phosphor
Dy doped SrF2 microcrystalline was prepared by co-precipitation technique. Thermoluminescence (TL) glow curve of γ irradiated SrF2:Dy phosphor consists of a main glow peak at 485 K with small shoulders at around 384 K and 590 K. The effects of different dopant concentrations and annealing regimes on...

| description | Dy doped SrF2 microcrystalline was prepared by co-precipitation technique. Thermoluminescence (TL) glow curve of γ irradiated SrF2:Dy phosphor consists of a main glow peak at 485 K with small shoulders at around 384 K and 590 K. The effects of different dopant concentrations and annealing regimes on TL sensitivity were investigated and the optimum conditions were achieved at 1 mol% of Dy dopant and annealing at 700 °C for 30 min. Initial rise, variable heating rate, isothermal decay and computerized glow curve deconvolution (CGCD) methods were applied to obtain kinetic parameters of the prepared material. TL sensitivity of this phosphor is about 10 times more than that of LiF;Mg;Ti (TLD-100). Based on the obtained results, the synthesized phosphor is appropriate for dosimetry applications.
•Highly sensitive SrF2:Dy thermoluminescent phosphor was produced by co- precipitation method.•Its sensitivity is about 10 times higher than that of LiF:Mg.Ti(TLD-100).•The kinetic parameters were obtained using different methods.•The fabricated phosphor is suggested to be used as thermoluminescent dosimeter. |
