Validity of repeated initial rise thermoluminescence kinetic parameter determinations

Spectral and kinetic analysis of thermoluminescence from manganiferous carbonatite

Thermoluminescence spectra of manganiferous carbonatite has been studied from 30 1C to 400 1C over the wavelength range from 200 nm to 800 nm. The natural thermoluminescence appears above 200 1C and shows continuous spectral distribution from 240 nm to 800 nm. Above 500 nm the emission appears in the form of line structure emission. These are reproduced by laboratory irradiation which also prod...

Thermoluminescence kinetic parameters of different amount La-doped ZnB₂O₄.

The kinetic parameters of 1%, 2%, 3% and 4% La-doped ZnB2O4 phosphors (i.e. ZnB2O4:0.01La, ZnB2O4:0.02La, ZnB2O4:0.03La and ZnB2O4:0.04La) synthesized by nitric acid method have been calculated. Thermoluminescence (TL) glow curves of ZnB2O4:La phosphors after beta-irradiation showed a very well defined main peak having the maximum temperature at around 200°C and a shoulder peak at around 315°C ...

Kinetic-based determinations in continuous-flow analysis

Introduction The automation ot analytical processes is becoming an increasingly important area in analytical chemistry and is a response to the growing complexity of the problems faced and to the need to cut down on expenses on

Thermoluminescence characteristics and kinetic analysis of copper doped magnesium sulfate in gamma irradiation

MgSO4:Cu phosphor was synthesized by solid state method. Optimum concentration of copper was determined at 0.1 mol%. Thermoluminescence characteristics of MgSO4:Cu was studied following gamma irradiation. A linear dose response was observed in dose range of 1Gy to 500Gy. Reusability of this sample was tested after 10 cycles of gamma irradiation and it revealed that the intensity remains approxi...
