“…Inorganic phosphors doped with rare earth ions have attracted extensive attention owing to their remarkable luminescence properties and applications. [1][2][3] As an efficient red luminescent activator, trivalent europium (Eu 3+ ) was widely doped in the hosts of titanate, 4,5 silicate, 6,7 aluminosilicate, 8 fluoride, [9][10][11] oxysulfide, 12,13 and metal oxide. 14 The synthesis methods include the high-temperature solid-state reaction method 15 and wet chemistry methods such as co-precipitation, 16,17 hydrothermal synthesis, [18][19][20] colloidal chemistry 21 etc.…”
