摘要

PURPOSE: A method for manufacturing metal oxide nanoparticle is provided to be applicable in the plastic substrate weak on heat by forming a thin film at relatively low temperature in range of the room temperature to about 100°C. A manufacturing method of the metal oxide nanoparticle is provided to make an electric component including the metal oxide. CONSTITUTION: A method of manufacturing metal oxide nanoparticle comprises: a step(S11) of preparing an alcoholic solution including basic chemical species; a step(S12) of preparing a metal oxide precursor solution; a step(S13) of reacting the metal oxide precursor solution with the mixture of alcoholic solution to form metal oxide nanoparticle; a step(S14) of refining the metal oxide nanoparticle. The alcoholic solution comprises C1-C6 alcohol and basic chemical species is selected in the group consisting of LiOH, NaOH, KOH, NH4OH, their hydrate and their mixture.
