Abstract
The present invention relates to a method for preparing a BaSnOthin film, comprising the steps of: a) precipitating an amorphous precipitate by adding an alkaline aqueous solution to a mixture solution comprising a barium salt, a tin salt, hydrogen peroxide, and an organic acid; b) preparing a crystalline BaSnOprecursor material by preheating the mixture solution containing the amorphous precipitate; c) preparing a dispersion solution by dispersing the crystalline BaSnOprecursor material in a polar organic solvent; d) coating the dispersion solution on a substrate; and e) preparing a BaSnOthin film of a perovskite structure by heat treating the dispersion solution coated on the substrate.
