ABSTRACT:
A method of producing a UV-emitting magnesium pentaborate phosphor is described. The method comprises combining a hydrated magnesium hexaborate with oxides of Y, Gd, Ce and Pr to form a mixture and firing the mixture in a slightly reducing atmosphere to form the phosphor. The hydrated magnesium hexaborate, which is preferably prepared as a precipitate, preferably has a formula MgB6O10.XH2O where X is from 4 to 6.
