| dc.description | This paper presents the results of the preparation and characterization of dysprosium-doped calcium sulfate (CaSO4:Dy) phosphor, which was obtained by homogeneous precipitation from calcium acetate Ca(CH3COO )2. Structural and morphological characteristics were studied using a scanning electronic microscope (SEM). The structure of all compounds was determined by X-ray diffraction method too. Thermoluminescence (TL) emission properties of CaSO4:Dy under gamma radiation effects were studied. This phosphor powder presented a TL glow curve with two peaks (Tmax) centered at around of 180 and 300 1C, respectively. The TL response of CaSO4:Dy as a function of gamma absorbed dose was linear in a wide range. Both emission and excitation spectrawere also obtained. Results showed that this new preparation method of CaSO4:Dy TL phosphor is less expensive, cleaner and safer than the conventional preparation method. | - |
