英文摘要	a new orange-yellow-emitting sr9mg1.5(po4)(7):eu2+ phosphor was prepared via high-temperature solid-state reaction. the structure and optical properties of it were studied systematically. sr9mg1.5(po4)(7):eu2+ can be well-excited by 460 nm blue ingan chips and exhibit a wide emission band covering from 470 to 850 nm with two main peaks centered at 523 and 620 nm, respectively, which originate from 5d-4f dipole-allowed transitions of eu2+ in different crystallographic sites. the sites attribution, concentration quenching, fluorescence decay analysis, and temperature-dependent luminescence properties were investigated in detail. furthermore, a warm white led device was fabricated by combining a 460 nm blue ingan chip with the optimized orange-yellow-emitting sr9mg1.5(po4)(7):eu2+. the color coordinate, correlated color temperature and color rendering index of the fabricated led device were (0.393, 0.352), 3437 k, and 86.07, respectively. sr9mg1.5(po4)(7):eu2+ has great potential to serve as an attractive candidate in the application of blue light-excited warm white leds.
