Plant growth LEDs have attracted broad attention in modern society, desperate for specific phosphors with a characteristic emission band. A novel Mn(4+) and Dy(3+) co-doped Y(3)Al(4)GaO(12) phosphor were successfully prepared through a conventional high-temperature solid-state reaction. A three band emission including red (625-700 nm), orange (550-607 nm) and blue (462-490 nm) is observed in these phosphors when excited under a near-UV lamp, which is ascribed to (2)E → (4)A(2) of Mn(4+), (4)F(9/2) → (6)H(15/2) and (4)F(9/2) → (6)H(13/2) of D...
