The effect of Nb codoping on the optical properties of the PbWO[sub 4]:Mo scintillator is investigated by radio- and thermoluminescence, scintillation decay, and light yield measurements. Steady-state radioluminescence efficiency of PbWO[sub 4]:Mo,Nb with optimized doping concentrations (2750 and 350 molar ppm, respectively) becomes up to 20 times higher with respect to that of undoped PbWO[sub 4] and is comparable to that of Bi[sub 3]Ge[sub 4]O[sub 12]. However, slow components down to several tens of microseconds appear in the time decay. Their existence may be related to the presence of traps monitored by thermoluminescence. © 2002 American Institute of Physics. [ABSTRACT FROM AUTHOR] |
