Luminescence of BaAl2O4:Mn2+,Ce3+ phosphor

d–f luminescence of Ce3+ and Eu2+ ions in BaAl2O4, SrAl2O4 and CaAl2O4 phosphors

“…Ce 3+ doped phosphors are used for fast scintillators and also as long lasting phosphorescent materials. Jia and co-workers [2] reported luminescence in BaAl 2 [3]. In recent, all kinds of lamps and display devices are being replaced by light emitting diodes (LEDs).…”

Ca5La5(SiO4)3(PO4)3O2:Ce3+,Mn2+: A Color-Tunable Phosphor with Efficient Energy Transfer for White-Light-Emitting Diodes

“…There have been several combinations of phosphors and LEDs to fabricate white LEDs, namely (a) a blue InGaN LED chip and a Y 3 Al 5 O 12 :Ce 3þ (YAG:Ce) phosphor, 1 (b) a UV LED chip and two, three, even four phosphors, [2][3][4] and (c) a UV LED chip in combination with a single-composition white-lightemitting phosphor. [10][11][12][13] As is well known, the Ce 3þ ion with the 4f configuration in solids shows efficient broad band luminescence due to the 4f-5d parity allowed electric dipole transition. However, this method faces serious problems of poor color rendition due to lacks of a red-emitting component, thermal quenching and narrow visible range.…”

Study of surfaces and morphologies of proteic sol–gel derived barium aluminate nanopowders: An experimental and computational study

“…For example, red fluorescence from Cr 3þ doped BaAl 2 O 4 as well as the influence of the surface area is reported by Singh et al [3]. Other doping ions have also been investigated for new photoluminescence and thermoluminescence properties; BaAl 2 O 4 : Mn 2þ , Ce 3þ [4], BaAl 2 O 4 : Eu 2þ [5e8] and BaAl 2 O 4 : Eu 2þ , Cr 3þ [9]. The BaAl 2 O 4 films doped with Eu 2þ and Dy 3þ [10] and doped separately with Tm 3þ , Tb 3þ and Eu 3þ [11] were studied for the photoluminescence and cathodoluminescence.…”
