Popis: | A series of phosphors PbGd1-xB7O13:xDy3+ (x = 0–0.14) were synthesized by the high temperature solid-state reaction method. The as-prepared products were characterized by powder X-ray diffractometer (XRD) and photoluminescence spectrometer (PL). The results indicate that PbGd1-xB7O13:xDy3+ exhibits two emission peaks: the blue emission at around 488 nm due to 4F9/2 → 6H15/2 transition and the yellow emission at around 572 nm due to 4F9/2 → 6H13/2 transition. The optimum doping concentration was found to be 6 mol% for Dy3+ ion. The commission international Del’Eclairage (CIE) chromaticity coordinates of the phosphors were about (0.394, 0.463), corresponding to yellowish color. |
