摘要
Disclosed herein is a method of stabilizing alpha-sialon phosphor raw powder, including the steps of: mixing alpha-sialon phosphor raw powder including Si3N4, AlN, a rare-earth metal oxide and calcium nitride (Ca3N2) as a calcium source and having Composition Formula represented by CaxSi12−m−nAlm+nOnN16−n:Rey (here, Re is an activator and is at least one selected from the group consisting of Eu, Ce, Tb, Yb, Sm and Dy, 0.3≦m≦1.0, 0.02≦y≦0.15, m=2x+3y); and heat-treating the alpha-sialon phosphor raw powder to convert the calcium source into a Ca—Al—Si—N based compound. This method is advantageous in that a reliable alpha-sialon phosphor having high photoluminescence intensity can be manufactured regardless of weather, season, environment and the like.
