(Ba,Sr)TiO3 nanocrystals with narrow size distribution and quasi-spheric shape were successfully prepared by glycothermal method. The synthesized products were characterized by XRD, TEM and Raman spectroscope. Chemical composition, crystal structure, particle size and crystallinity are strongly influenced by the factors including butanediol/water ratio, temperature and Ba/Sr ratio of the liquid media. The results manifest that the glycothermal process may provide a simple route to the synthesis of monodispersed BST nanocrystals without mineralizing agents.
