Abstract
A method for making the metal oxide includes the following steps: mixing a metal nitrate with a solvent of octadecyl amine, and achieving a mixture; agitating and reacting the mixture at a reaction temperature for a reaction period; cooling the mixture to a cooling temperature, and achieving a deposit; and washing the deposit with an organic solvent, drying the deposit at a drying temperature and achieving a metal oxide nanocrystal. The present method for making a metal oxide nanocrystal is economical and timesaving, and has a low toxicity associated therewith. Thus, the method is suitable for industrial mass production. The metal oxide nanocrystal material made by the present method has a readily controllable size, a narrow size distribution, and good crystallinity.
