摘要：
A silicate phosphor having a coating layer comprising a fluorine-containing compound on its surface which is obtained by a method of heating a mixture of 100 weight parts of a silicate phosphor and 0.5-15 weight parts of ammonium fluoride at a temperature in the range of 200 to 600° C. exhibits high light emission intensity and high moisture resistance.
