Experimental set-up for measurement of luminescence characteristics at X-ray excitation

摘要

Modem scientific investigations of scintillation characteristics in new materials make high demands to experimental set-ups. For any in-depth study of new materials complex experimental devices are needed. In this work, we present our experimental complex for studying the main scintillation properties of luminescent materials. As an object of investigation for a demonstration of this set-up possibilities the Pr-doped phosphors have been chosen.The developed device allows us to hold the following measurements: emission spectra, kinetics, relative light output under steady state and pulsed X-ray excitations, thermo-stimulated luminescence and afterglow. Some new results in the Pr-doped phosphors' luminescent characteristic investigations which have been obtained via this facilities are presented in this paper. (C) 2004 Elsevier Ltd.
