Structure, energy transfer, and luminescence properties of NaLaMgWO6: Tb3+,Eu3+ phosphors for solid-state lighting

Color tunability of NaLaMgWO6:Mn4+, Tb3+ phosphor and its potential application in temperature sensor and wavelength detector

“…The La 3+ site in the matrix can be replaced by Tb 3+ and other trivalent rare earth ions, and the [WO6] octahedrons can provide octahedral sites suitable for Mn 4+ ions. The Mn 4+ doped NaLaMgWO6 red phosphors and the Tb 3+ doped NaLaMgWO6 phosphors have been widely reported [23][24][25][26]. As far as we know, however, there are no reports so far about NaLaMgWO6:Tb 3+ , Mn 4+ co-doped dual-emitting phosphor.…”

Luminescence and Energy Transfer of Li2Y4(MoO4)7: Ln3+ (Ln = Dy, Eu) Phosphors

“…[7][8][9][10] Particularly, these phosphors with different emission colors could be created through selecting one appropriate lanthanide ion and proper control of their dopants. The single-component rare-earthdoped phosphors such as the red emission color of NaSrLa(MO 4 ) 3 : Eu [M = Mo and W] 11 and Ba 3 Y 4 O 9 : Eu 12 derived from the 5 D 0 → 7 F 1,2 transitions of Eu 3+ ion, the adjustable ones of Ca 3 Sc 2 Si 3 O 12 : Dy, 13 Ca 3 MgSi 2 O 8 : Dy 14 and SrLaGa 3 O 7 : Dy 15 caused by the ratio of magnetic and electric dipole transitions of Dy 3+ ion, the blue ones of NaCaBO 3 : Tm, 16 ZnB 2 O 4 : Tm 17 and Li 6 CaLa 2 Nb 2 O 12 : Tm 18 beacuse of 1 D 2 → 3 F 4 transition of Tm 3+ ion, the green ones of NaBaY(BO 3 ) 2 : Tb and NaLaMgWO 6 :Tb 19 on account of 5 D 4 → 7 F 5 transition of Tb 3+ ion 20 have been investigated.…”
