Electrophysical properties and photoconductivity of several binary (PbTiO3, PbZrO3, PbHfO3) and ternary (Pb2ScNbO6, Pb2InNbO6) lead-containing perovskite-type oxides were investigated. Band gap energies for all studied compounds were measured to be somewhat smaller than for its perovskite analogs not containing lead. This fact is ascribed to a specific configuration of the outer electronic shell of lead.Owing to high photosensitivity of the lead-containing perovskites, a considerable effect of electronic subsystem (in particular of the non-equilibrium carriers) on crystal properties both in ferroelectric and antiferroelectric crystal phases was observed.
