چکیده انگلیسی
The effects of various experimental parameters have been investigated in order to optimize potential dosimetric applications of optically stimulated luminescence from LiF:Mg,Ti. These included: (i) the most appropriate filter in the emission channel for optimization of signal to noise ratio, (ii) the effect of sample thickness and self-absorption, (iii) the effects of high dose pre-irradiation for sensitization/radiation damage on the emission spectra and (iv) the effects of the preirradiation annealing/cooling procedures. Two methods have been used to measure the time-stability of the F3+ and F2 emission bands: (i) via the measurement of the OSL intensity (520 or 640Â nm band) as a function of the laser illumination time and (ii) via the measurement of the emission spectra in the range 500-700Â nm after 30Â min illumination by 300Â mW laser light (457Â nm). In addition the OSL dependence on the stimulation light intensity has also been investigated.
