ABSTRACT:
An improved method for a single step firing synthesis of borate phosphors wherein at least about half the amount of a volatile, low melting point, boron source such as boric acid or boron oxide is replaced with an equivalent amount of boron nitride. The method having the advantages of a single step firing and providing better control over the stoichiometry of the phosphor.
