摘要

SrBi₂Nb₂O₉ (SBN) ferroelectric thin films were fabricated using plasma assisted laser deposition (PLD). The band-gap energy was determined to be 3.60 eV. A photoluminescence peak at 0.78 μm was observed whose intensity decreased with decreasing temperature, when excited with subband-gap energy. A mechanism for the observed photoluminescence, a Nb⁴⁺ -O^- exciton in the NbO₆ octahedron was suggested.
