Abstract
The effect of La dopant on the scintillating properties of lead tungstate has beenfound to depend on the doping concentration. In this work the conductivities of aseries of PWO:La single crystals were measured and explained by a change in dopingmechanism. We propose that the oxygen vacancy is the main type of chargecarrier at all doping levels from room temperature to 1000 °C.Offering high conductivity and low activation energy, heavily doped PWO:La mayserve as a fast ion conductor of merit.
