Manufacturing Method of Sn based Oxide Semiconductor Nano Powder And Manufacturing Method of Opto-electronic Electrode Using Sn based Oxide Semiconductor Nano Powder

摘要

Disclosed herein is a method of preparing a ternary oxide semiconductor compound, including the steps of: dissolving an inorganic salt source including Sn and an inorganic salt source including at least one selected from the alkali earth metal group consisting of Ba, Sr and Ca in a mixed solvent of water and hydrogen peroxide to form a mixed solution; precipitating the mixed solution by changing the PH thereof to obtain a precipitate and then aging the precipitate; and drying and then annealing the aged precipitate to prepare MSnO3 powder (here, M includes at least one selected from the group consisting of Ba, Sr and Ca). The method is advantageous in that a nanosized ternary oxide semiconductor compound having a uniform particle size distribution can be prepared.
