The conditions for strontium titanate (SrTiO3, ST) nucleation and particle growth were investigated for preparation of ST/ barium titanate (BaTiO3, BT) complex nanoparticles. The conditions with and without ST nucleation were clarified. Epitaxial growth of ST layer on the BT substrate particles was studied using both conditions. Unfortunately, the ST/BT complex nanoparticles with heteroepitaxial interface were not prepared, but a new two-step solvothermal reaction method was developed. Finally, the ST/BT complex nanoparticles without heteroepitaxial interface were successfully prepared.

Abstract The ferroelectric barium strontium titanate (Ba1-xSrxTiO3) is a homogeneous solid solution prepared from the mixture of barium titanate (BaTiO3), strontium titanate (SrTiO3) and titanium (IV) isopropoxide. Barium strontium titanate (BST) nanomaterials with improved permittivity and dielectric properties due to their nano-properties have attracted great interest for extensive and versatile applications as super capacitors, dielectrics, ceramics and catalysts. Introduction of metal ion dopants into the parent system of BST significantly alters its structural, morphological, electrical, optical and dielectric characteristics. This review is aimed at addressing synthesis, characterization methods, photocatalytic and electrical applications of metal ions doped BST nanomaterials. The effect of doping BST, through metal ions, on its properties and application with most probable reasons have been thoroughly discussed.
