Abstract
Measurements of diffuse reflectance spectra in the range ofλe 〈400, 2500〉 nm were used for study of the effect of doping with iron oxide, chromium oxide and manganese oxide on the properties of polycrystalline Pb(Zr0.60Ti0.4) O3 solid solution. On the basis of analysis of experimental results it is concluded that mentioned oxides in the amount of 2 at.% interact at 1000 °C with perovskite crystal lattice of studied solid solution, creating local level in its forbidden gap. The values of charge carrier excitation energy found from these levels are 2·48 eV in the case of iron oxide doping, 1·68 eV in the case of chromium oxide and 1·44 eV in the case of manganese doping.
