HIGH EFFICIENCY MANUFACTURING METHOD OF NANO PHOSPHOR

摘要

A method for manufacturing nano phosphor at high efficiency is provided to prepare nano-sized phosphor while reducing photoluminescence intensity of commercialized micro-sized phosphor by adding a simple process. A method for manufacturing nano phosphor at high efficiency comprises the steps of: (i) adding micro phosphor in an acid solution, and then stirring the added mixture, wherein the acid solution is obtained by diluting acid in ultrapure water; and (ii) separating only phosphors after (i) step, and then the separated phosphors in the ultra-pure water and dispersing it in a ultrasonic atmosphere.
