Description :
In this paper thermoluminescence displayed Sr2B5O9Cl:Dy is discussed. Modified solid state diffusion method was used for the preparation of phosphor.Dy (0.5 mol%) doped Sr2B5O9Cl after exposure to γ-irradiation is studied for which revealed a prominent glow curve at 261°C Trapping parameters and their estimated error values have been calculated by Chen‟s peak shape method, initial rise method and whole glow peak method. Values of activation energies estimated by all these techniques are comparable.
