Abstract

The present paper reports the thermoluminescence (TL) behaviour of Li6Gd(BO3)3:Dy3+phosphor on exposure to carbon ion beam. The phosphor was synthesized by combustion technique with varying Dy3+concentrations. The TL glow curve of the phosphor, consist of prominent and well defined TL peaks at 131oC and 228oC for carbon ion fluence of 5 x 1010 ions/cm2. Nature and peak position remains stable for different activator concentrations and fluence, however change is noticed in TL intensity. TL intensity is found maximum for Dy3+ concentration of 0.1 mole% at the fluence of 5 x 1010ions/cm2. This TL curve was analyzed by Glow curve deconvolution (GCD) functions. Activation energy (E), order of kinetics (b) and frequency factor (s) were determined using Chen’s peak shape method and theoretical curve was drawn using GCD functions.
