F-centre/Mn complex photoluminescence in the fluoroperovskites AMgF3:Mn (A = Na, K, or Rb)
Photoluminescence (PL) measurements were made on AMgF3:Mn (A = Na, K, or Rb) before and after X-ray irradiation. F-centre/Mn (F/Mn) complexes were seen in all samples after irradiation where the energy levels are perturbed from the original Mn2+ levels. The perturbed energy of each level depends on...
