Method for treating nano-phosphor with atmospheric pressure plasma

摘要

Provided is a new treatment method improving light emitting properties of nanophosphor and controlling a change over time. The method for treating nanophosphor of the present invention comprises the steps of: preparing oxide-based nanophosphor; and changing surficial properties of the oxide-based nanophosphor or improving crystallinity by treating the oxide-based nanophosphor by generating atmospheric pressure plasma. According to the present invention, surficial defect of nanophosphor can be removed and the crystallinity can be improved to have an effect of improving the light emitting properties and can control changes in crystal structure when using phosphor, thereby controlling change over time.
