PROBLEM TO BE SOLVED: To provide a method for preparing a ZnO particle to which a nano scale structure is imparted where an effective component or the like can be disposed and of which the shape is controlled into a hexagonal pyramid shape, hexagonal plate shape and disc shape of about 5 μm in microscale, by using a molecule assembly fromed by a surfactant as a template, as a result of a study wherein since control of the shape of a zinc oxide crystal is main in microscale in the prior art and control in nano scale is not reported, the inventor makes a study for the purpose of simultaneously imparting a structure of nano scale capable of retaining a drug component or the like to the zinc oxide crystal being controlled in microscale.SOLUTION: A method for producing a zinc oxide crystal is provided. According to the method, the zinc oxide crystal is produced which has a multilayered structure by using a ZnO precursor aqueous solution obtained by adding a ZnO precursor to an aqueous solution that contains surfactant molecules and is pH controlled to alkali. |
