Abstract:
In the present work BaCa2Al8O15:Dy3+ phosphor has been prepared by combustion method. Powder X-ray diffraction (XRD) analysis and thermoluminescence (TL) measurements were used for characterization. The trapping parameters namely activation energy and order of kinetics were calculated using peak shape and the results are discussed. Thermoluminescence (TL) glow curves of gamma irradiated BaCa2Al8O15:Dy3+ phosphor exhibit a single broad glow peak at 163.90 °C. The activation energy was found to be 0.72 eV. Frequency factor was found to be 2.49 x 106 s-1.
