摘要

An objective is to control damage of a phosphor caused by an etching solution. Disclosed is a method for manufacturing a phosphor having the steps of: crushing phosphor particles via a crushing treatment process, and surface-treating phosphor particles dispersed in a solvent by adding an etching solution via a surface treatment process, wherein an adding speed of the etching solution is in a range of 1.2 x 10 -16 - 7.0 x 10 -15 mol/min. per 1 m 2 of specific surface area of the phosphor particles.
