Hydrothermal synthesis and photoluminescence properties of Eu3+ doped Na4La2(CO3)5 rod-like nanophosphors

Mn4+-activated BaLaMgSbO6 double-perovskite phosphor: a novel high-efficiency far-red-emitting luminescent material for indoor plant growth lighting

“…Recently, red-emitting luminescent materials doped with rareearth ions (such as Eu 3+ , Eu 2+ , Ce 3+ ) and transitional metal ions (such as Mn 4+ and Cr 3+ ) have attracted much attention due to their promising applications in lighting and displays. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Mn 4+ ion with a 3d 3 electron conguration belongs to the transitional metal ion, and in recent years Mn 4+activated red-emitting phosphors have been widely reported for warm-white light-emitting diodes (LEDs) towards general lighting applications. [15][16][17][18][19] Generally, Mn 4+ ions can substitute for W 6+ , Sn 4+ , Sb 5+ , Al 3+ , Ge 4+ , Ta 5+ , and Ti 4+ ions in the octahedral or distorted octahedral systems.…”
