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.
