Abstract

1450226 Luminescent materials GENERAL ELECTRIC CO 28 March 1974 13903/74 Heading C4S Mg aluminate gallate phosphor activated with Mn contains a stabilizer M to avoid loss of brightness when the phosphor is heated in air, M is either Ca, Sr or Ba phosphate or phosphate ion. The phosphor and its method of preparation are similar to those described in Specification 1,382,530 to which a Statutory reference is made. Reference has been directed by the Comptroller to Specification 1,382,530.
