dc.description.abstractPhotorefractive barium titanate and barium-calcium titanate crystals with the congruently melting composition (Ba0.77Ca0.23TiO3) doped with iron are annealed in a hydrogen atmosphere at various temperatures. The samples are studied with electron paramagnetic resonance (EPR) and optical absorption both performed separately as well as simultaneously before and after illumination. The samples are electron conductive and the charge Fe2+/3+ at room temperature ir governed by only one level identified by photo-EPR as The optical absorption of Fe2+ in BaTiO3:Fe is found to be at 2.1 eV and in (Ba0.77Ca0.23TiO3) Fe at 1.9 eV.
