On the investigation of the energy transfer in Ca9Lu(PO4)7:Eu2+,Mn2+,Nd3+

High performance of broad excitation and narrow emission green phosphor NaAl11O17:Eu2+, Mn2+for backlight displays

“…Subsequently, it returns to the ground state 6 A 1 ( 6 S) in the form of non-radiative transition, which gradually enhances the green emission of Mn 2+ ions. 48,49 In the Na 0.8 Al 11Ày O 17 : 0.20Eu 2+ , yMn 2+ system, the emission intensity of Mn 2+ is greatly improved through the energy transfer process.…”

Preparation and properties of Eu2+/Eu3+ co-activated Ca9Lu(PO4)7 phosphors for multichannel photoluminescence

“…Presently, there have been reports on Ca 9 Lu(PO 4 ) 7 doped with Eu 3+ , co-doped with Eu 2+ and Mn 2+ , co-doped with Ce 3+ and Mn 2+ , and co-doped with Eu 2+ , Mn 2+ and Nd 3+ as promising hosts of luminescent materials; Ca 9 Lu(PO 4 ) 7 doped Pr 3+ or Ce 3+ as scintillating materials; and Ca 9 Lu(PO 4 ) 7 :Tb 3+ ,Mn 2+ for potential applications in 3D plasma display panels (PDPs). 1,[26][27][28][29][30] However, the optical characteristics of Eu 2+ /Eu 3+ -activated Ca 9 Lu(PO 4 ) 7 for white light-emitting diode (w-LED) applications have not been investigated yet.…”
