Kinetic Analysis of TL Spectrum of ϒ-IrradiatedSrAl2O4:Eu2+, Dy3+ Nanophosphor
Abstract- Thermoluminescence is a simple technique for studying the distribution of artificially created or naturally occurring point defects. In present work we are reanalyzing the Thermoluminescence response of Eu2+, Dy3+ doped SrAl2O4 nanophosphor at different irradiation dose of ϒ-rays, 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. As per new model order of kinetics depends on extent of retrapping and from reanalysis we can infer that all the reported TL responses of material under consideration are retrapping dominant process.
