Abstract:
In this work, we have employed for the analysis of thermoluminescence TL glow
curves of Zinc oxide ZnO materials. The continuous promotion in numerical methods has greatly helped to solve the complex Thermoluminescence TL kinetic equations which can not be solved analytically. In this thesis, the properties of the thermoluminescence glow curves of zinc oxide ZnO has been employed theoretically
in view of first order kinetics. As activation energy increase the glow curve shifts to
higher temperatures with a decrease in the height . For higher E values or deeper
traps more energy or higher temperature is needed to release the charge carriers.
Therefore, Similar changes can be noticed as the parameter S is varied but now in
the opposite way: As frequency factor S increases the peak shifts to lower temperatures with an increase of the height and a decrease in width. A trapping center with
a high frequency factor needs less energy or it needs lower temperature to free a
charge carrier.
