Abstract
A study of the optical properties of Mn+2 in commercial halophosphate phosphors has revealed that the Mn+2 is located on four distinguishable sites: on the simple Ca(I) site, on the simple Ca(II) site, on a Ca(II) site adjacent to an antimony‐oxygen pair, and on a Ca(II) site adjacent to a chlorine ion in those phosphors containing chlorine. The Mn+2 fluorescence that results when the excitation is via energy transfer from antimony ions is primarily due to Mn+2 situated on a Ca(I) site, with smaller components due to Mn+2 located on the other sites observed.Keywords
