ETIMATION OF THE ACTIVATION ENERGY OF TRAPS IN THERMOLUMINESCENCE FROM ABSORPTION CURVES

Abstract

In this report we have studied the correlation between the thermoluminescent curves and the absorption curves as a function of the temperature obtained from different TL materials which are common-used in radiation dosimetry and dating technicques. The TL glow curves of these materials can be obtained from the absorption measurement. The activation energy E of the constructed TL glow peaks of arbitrary order of kinetics (1 £ l £ 2) then can be deduced by using a modified Chen's half width method as well as the deconvolution method. The obtained values are compared with those obtained from conventional method.
