Abstract :
Decay kinetics of the green emission of PbWO4:Mo crystals is measured in wide temperature range 0.4–400 K. Experimental data are satisfactorily fitted by two excited-state level model. Rapid decay-time shortening at higher temperatures is explained by thermal ionization of (MoO4)2−center. This hypothesis is confirmed by thermoluminescence measurements. The same value, 0.26 eV, of activation energy of this process is evaluated from both the thermoluminescence measurements and decay kinetics modeling.
