fluoride compounds are found to be effective in decreasing the preparation temperature and obtaining good luminosity. However
the residue of the fluoride in the phosphors always results in apparent decay.An improved method in which boric acid is used as a flux instead of the fluoride is presented here. In comparison with the ordinary process the maintenance of the phosphor is obviously improved while the preparation temperature and luminosity keep unchanged.
