Perovskite, an attractive subject in many research areas, has been well-known for its multifunctionality. Especially, perovskites with noncentrosymmetric (NCS) structure are of great interest for the unique characteristics such as ferroelectricity, piezoelectricity, and nonlinear optical (NLO) properties. One of the NCS perovskites, Na0.5Bi2.5Nb2O9 with a polar structure is expected to have interesting NLO properties. Since it has been studied only on phase transition and other electrical properties, we have investigated a more detailed NLO property changes by substituting lone pair cations with lanthanide elements. The doped compounds have been successfully synthesized by solid state reactions. The crystal structures were determined by the Rietveld refinement. Crystal structures and characterizations of the reported compounds are presented.
