In this study Dy doped LiMgBO3:xDy3+ phosphor has been synthesized by conventional solid state reaction method for different concentrations of Dy (x = 0, 0.0005, 0.001, 0.002, 0.005, 0.01 and 0.02). The synthesized phosphor was characterized for its TL properties that included TL glow curves and TL response for different concentrations of Dy after exposure of 700 Gy gamma rays. Further the kinetic parameters: Activation energy (E) and Order of kinetics (b), were determined using Chen’s Peak Shape method and theoretical curves were generated using GCD glow fit. Good match of kinetic parameters have been observed between two methods. Simple glow curve structure and good TL response can make this phosphor a better candidate for future work on radiation dosimetry.
