Abstract
Abstract BaMgAl 10 O 17 :Eu 2+ (BAM) phosphors were prepared via the molten salt synthesis (MSS) method. The NaCl–KCl eutectic mixture and LiF were used as the molten salt and flux, respectively. X-ray powder diffraction (XRD) patterns indicate that the BAM phase is formed above 1200 °C and that the addition of LiF leads to an obvious improvement in crystallinity. The emission intensity of the BAM phosphor with 10 wt% LiF is about 85% higher than that of the phosphor without LiF and about 200% higher than that of the phosphor without molten salt and LiF. Scanning electron microscopy (SEM) reveal that the as-prepared phosphors have good crystallinity and regular morphology, and most importantly, they are not aggregated. Li + doping is benefit for the thermal stability and results in a slightly longer decay times of 1.17 μs.
