An Investigation on Thermoluminescence Properties of C6+ Ion Beam-Irradiated K2Ca2(SO4)3:Eu,Cu

Potassium calcium sulfate (K 2 Ca 2 (SO 4 ) 3 :Eu,Cu) co-doped with Eu 2+ and Cu 2+ (1000 ppm each) has been prepared by the co-precipitation method. Compound confirmation was carried out by X ray diffraction, and the average crystallite size was 61 nm, calculated by the Williamson–Hall plot method....

Description
Summary:Potassium calcium sulfate (K 2 Ca 2 (SO 4 ) 3 :Eu,Cu) co-doped with Eu 2+ and Cu 2+ (1000 ppm each) has been prepared by the co-precipitation method. Compound confirmation was carried out by X ray diffraction, and the average crystallite size was 61 nm, calculated by the Williamson–Hall plot method. The presence of dopants was confirmed by the photoluminescence emissions and excitation spectra. This nano-crystalline phosphor has been investigated for its dosimetric applications by studying its thermoluminescence (TL) properties after being irradiated with ion beams (C 6+ ) at different fluences of different energies (65 MeV, 75 MeV, and 85 MeV). Also, the co-doped phosphor was compared with the singly-doped K 2 Ca 2 (SO 4 ) 3 :Eu in terms of its TL intensities, and it showed a higher TL sensitivity. Moreover, it showed a good dose response only for a low-energy C 6+ ion beam.
