Luminescence of BaAl2O4:Mn2+,Ce3+ phosphor
چکیده انگلیسی
Powder samples of barium aluminate doped with Mn2+ and Ce3+ were prepared by solid-state reaction method and their photoluminescence and thermoluminescence properties were studied. Substitution of Ca/Sr in place of Ba resulted in enhanced emission from Ce3+ ions without changing the spectral profile. Cerium efficiently sensitized the manganese luminescence in barium aluminate. Photoluminescence and thermo luminescence observations have indicated the presence of Vk3+ defects in undoped barium aluminate. However, Barium aluminate (either undoped or doped with manganese) did not exhibit long afterglow.
