ResumoAntimony may be present at calcium sites in the halophosphate lattice with anion (oxygen) compensation or cation (sodium) compensation, or as a SbCl3 vapor-doped activator. Oxygen compensated antimony is present at calcium (II) sites with the oxygen substituting for the adjacent halide ion. The antimony-oxygen system thus formed has its own unique emission, excitation, and decay properties. Sodium compensated and vapor-doped antimony in halophosphate have similar luminescent properties which are, however, distinctly different from those of oxygen compensated (normal) phosphors. Antimony which is not oxygen compensated emits at ∾400 nm and probably substitutes at the calcium (II) site also.
