Luminescence studies of Ba1−xMg2−y(PO4)2:xEu2+, yMn2+ phosphor

“…Resonance-type energy transfer generally plays a central role in the Eu 2+ and Mn 2+ co-doped host matrix, such as BaMg 2 Si 2 O 7 [17], BaZnP 2 O 7 [18] and Ca 5 MgSi 3 O 12 [19], and so on. The Eu 2+ or Mn 2+ singly doped BaMg 2 (PO 4 ) 2 phosphor emits blue or red light, so it is possible to obtain a phosphor with double color emission by the introduction of Eu 2+ and Mn 2+ if energy transfer exists.…”

Long Persistent Afterglow Luminescence in Gd₃Al₃Ga₂O₁₂:Ce³⁺, Green Emitting Aluminate Phosphor

“…The alkaline rare earth aluminate phosphors such as SrAl2O4:Eu2+, Dy3+, and CaAl2O4:Eu2+, Nd3+, are becoming very famous for their persistence is much higher than the older LL phosphors which were used radioactive material for the stimulation and longer persistence [4]. The human eye can easily see the green light emission of these phosphors even if there is no light present [5]. The YAG phosphor was firstly invented by Blasse and Brill in the year 1967, which is one of the applications in cathode ray tube phosphors, they also invented that this phosphor emits in the yellow region if it is given blue light excitation.…”
