Synthesis and luminescent properties of nonaggregated YAG:Ce3+ phosphors via the molten salt synthesis method

In this work, we synthesized nonaggregated YAG:Ce3+ phosphor powders using the molten salt synthesis method. The effects of synthesis temperature and time on the crystallization process, microstructures, and luminescent properties of the YAG:Ce3+ phosphors were studied. The results indicate that pure YAG:Ce3+ phosphors can be obtained at about 400 °C using NaNO2–KNO2 as the molten flux. Optimal synthesis conditions and Ce3+ doping concentration for the best luminescent properties for YAG:Ce3+ phosphors were determined.
