Abstract

Three relatively sharp FIR absorption bands of Ce3+ in Strontium Barium Niobate (SBN) are observed in the 2000-3000 cm(-1) region. A subband structure of these bands indicates three slightly inequivalent positions of the Ce3+ in the SBN crystal lattice. The concentration and temperature dependence of these bands is investigated.
