    • 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.
    • 提供了一种改善纳米荧光体的发光性能并控制随时间变化的新的处理方法。 本发明的纳米荧光粉处理方法包括以下步骤:制备氧化物基纳米荧光体; 并通过生成大气压等离子体处理氧化物基纳米荧光体,改变氧化物基纳米荧光体的表面性质或改善结晶度。 根据本发明,可以除去纳米荧光体的表面缺陷,并且可以提高结晶度以具有改善发光性能的效果,并且可以在使用荧光体时控制晶体结构的变化,从而控制随时间的变化。
