Formation of barium strontium titanate thin films via electrophoretic deposition process.
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.
