Kinetic Study of TL Glow Curve of Natural Fluorite

Author: Dr.Devendra Prasad

Category: Engineering, Science and Mathematics

Abstract:

Phosphor materials are very useful for display devices as well as for dosimetric uses. Characterization of material is must for selection of suitable one. Thermoluminescence is one of the most efficient and convenient tool for characterization of material. In the present paper we reconsider the Thermoluminescence studies of Natural Fluorite and ϒ- irradiated Natural Fluorite material, already reported in literature, to evaluate order of kinetics involved. Here a new method of analysis is adopted for the analysis of Thermoluminescence glow curves in order to evaluate order of kinetics. Order of kinetics involved in process depends on extent of retrapping. It is found that order of kinetics increases with irradiation dose.

Keywords: Thermoluminescence, Orders of kinetics, Phosphors, Irradiation Dose, Retrapping.
