Contribution à la chimie des halophosphates de calcium

Laboratoires de Recherches Philips, Eindhoven

Detailed study of the secondary reactions during the preparation of calcium halophosphates activated by Sb 3+ or Mn2+, in order to suppress the formation of Sb5+ or Mn3+ ions, or of free Sb2O 3 and Mn3O4, the effect of which is to lower the quantum efficiency.
