مستخلص: |
The rare earth doped aluminates and standard phosphor CaSO4:Dy were synthesized by urea fuel combustion and co-precipitation method respectively. The low-resolution SEM micrographs that the powders show many agglomerates. In order to confirm the chemical homogeneity of the phosphor sample by EDX spectra. The EDX study of the phosphors were confirmed the presence of doping rare earth metal Eu and Dy in host matrix compounds. The phosphors ZnMgAl10O17:Eu, BaMgAl10O17:Eu,Dy, SrMgAl10O17:Eu, Dy, CaMgAl10O17:Eu, Dy, BaMgAl10O17:Eu, and BaMg2Al16O27:Eu shows prominent TL peak near ∼187 °C and its intensity is higher as compared to CaSO4:Dy TLD phosphor. The glow curves for these hexa-aluminate samples are nearly identical. In short, the TL-intensity is found to be comparable and higher with that of CaSO4:Dy. Therefore, the reported aluminate samples having good intensity would be further investigated in respect of dose dependence, and then it may be used as TLD phosphors of ionization radiations.
