Abstract:
A phosphor composition is disclosed. A phosphor composition, comprises at least 10 atomic % bromine; silicon, germanium or combination thereof; oxygen; a metal M, wherein M comprises zinc (Zn), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), or combinations thereof; and an activator comprising europium. The phosphor composition is formed from combining carbonate or oxides of metal M, silicon oxide, and europium oxide; and then firing the combination. A lighting apparatus including the phosphor composition is also provided. The phosphor composition may be combined with an additional phosphor to generate white light.
