Influence of γ-dose, dopant/codopant and heating rate on thermoluminescence properties of CaWO{sub 4} phosphors
- Department of Applied Physics, Indian School of Mines, Dhanbad 826004 (India)
A series of Ca{sub 1-2x}K{sub x}Dy{sub x}WO{sub 4} (x = 0.02, 0.03, 0.04) phosphors were prepared by solid state reaction method and their thermoluminescence properties were investigated. Before thermoluminescence measurements, the sample was heated to 300°C for 1hour and then quenched to room temperature to erase out all the previous radiation memory. The prepared phosphors were irradiated by γ-ray in the dose range 1KGy–5KGy and their glow curves were recorded at an uniform rate of 5°C/s. In order to see the effect of heating rate as well as concentration of dopant/codopant, TL glow curves were also recorded by heating the samples at the rate of 3°C/s and 7°C/s as well as by varying the concentration x = 0.02, 0.03, 0.04.
