title: Formation of barium strontium titanate thin films via electrophoretic deposition process.
abstract: Synthesis of crystalline barium stronium titanate (Ba(0.6)Sr(0.4)TiO(3)) nanoparticles and subsequent formation of thin films have been carried out. The crystalline products were confirmed by X-ray diffractometry. Uniform Ba(0.6)Sr(0.4)TiO(3) thin films were formed by using electrophoretic deposition method (EPD) under a 0.3 to 5 V dc bias for 10 min to 1 h. Ba(0.6)Sr(0.4)TiO(3) nanoparticles having an average crystallite size of 20 to 50 nm, and Ba(0.6)Sr(0.4)TiO(3) thin films with thickness of 150 nm to 4 mum were obtained. A scanning electron microscope (SEM) and transmission electron microscope (TEM) were used to characterize the morphologies of nanoparticles and thin films. The results show that the EPD process route is a rapid, cost-effective alternative for forming Ba(0.6)Sr(0.4)TiO(3) thin films.
