摘要: The parametrization and optical properties such as absorption, photoluminescence (at 300 K 77 K) lifetimes of the lasing transition (5D0 to 7F2) EuF3 (1 M%)-doped heavy metal fluoride glass (HMFG) systems of: 48ZrF4+24BaF2+7AlF3+20RF where RF=LiF, NaF KF are studied. These Eu3+ glasses have shown red colour emission from their surfaces soon they illuminated by UV light. By applying Judd-Ofelt theory measured level quantum efficiency ( eta ) has been determined. Based on luminescence described in paper it is suggested that a with composition 48ZrF4+24BaF2+7AlF3+20NaF+1EuF3 would be an ideal system.
