✦ Synopsis

PbMoO 4 :Nd 3 + and PbWO 4 :Nd 3 + single crystals were grown by the Czochralski method. The Nd 3 + doping was performed by means of isostructural and non-isostructural compounds. Co-doping was also used. The spectral-kinetic characteristics of PbMoO 4 :Nd 3 + and PbWO 4 :Nd 3 + crystals were studied. Dielectric measurements were carried out at various temperatures ranging from 100 to 500 1C and at various frequencies ranging from 25 Hz to 1 MHz using the parallel plate capacitor method. Parameters of the dielectric relaxation process are determined. The possible mechanism of charge compensation is discussed.
