Plant growth LEDs have attracted broad attention in modern society, desperate for specific phosphors with a characteristic emission band. A novel Mn4+ and Dy3+ co-doped Y3Al4GaO12 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 2E → 4A2 of Mn4+, 4F9/2 → 6H15/2 and 4F9/2 → 6H13/2 of Dy3+, respectively. The three emiss...
