TSL Properties of γ-irradiated BaS:Bi Nanostructures

Author: Dr. Devendra Prasad

Category: Engineering, Science and Mathematics

Abstract:

Thermally Stimulated Luminescence is a simple technique for studying the distribution of artificially created or naturally occurring point defects. In present work we are reconsidering the these studies on nanostructures of Bismuth doped Barium Sulphide in accordance with new method of analysis. Orders of kinetics for different glow curves are recalculated. Order of kinetics values are not same as already reported in literature. The results of different doses and different heating rates on glow curves have been discussed. Effect of various heating rates on thermally stimulated luminescence response of nanocrystalline BaS : Bi are found to be in agreement with new suggested method.

Keywords: Thermally Stimulated Luminescence; Orders of kinetics; Glow Curves; Irradiation Dose; Heating Rate.
