Abstract

PURPOSE: To obtain a phosphor having improved fluorescent brightness and retentivity of luminous flux, by adding a chlorine compound or a combination thereof with a fluorine compound to a mix stock of a terbium-activated yttrium silicate phosphor and firing the resulting mixture.
CONSTITUTION: To a mix stock of a terbium-activated yttrium silicate phosphor is added a chlorine compound or a combination thereof with a fluorine compound. The resulting mixture is fired so as to produce a phosphor having a fluorine content of up to 2wt%, a chlorine content of 0.05W2.8wt% and a total content of chlorine and fluorine of 0.05W3.0wt%.
