Characterization of YVO_4:Eu~(3+), Sm~(3+) red phosphor quick synthesized by microwave rapid heating method

摘要

Eu~(3+)- and Sm~(3+)-doped YVO_4 phosphors were produced by microwave heating reaction. When the microwave heating method was used, the particle size was very small and the particles tended to agglomerate. However, as the main heating time increased, the particle size increased and the agglomeration decreased. In the photoluminescence analysis, the emission spectrum exhibited a weak band for ~5D_0 →~7F_1 at 594.91 and 602.33 nm and strong sharp peaks at about 616.77 and 620.08 nm due to the ~5D_0 → ~7F_2 transition of Eu~(3+). Microwave synthesis can provide a product without long time sintering as well as good homogeneous distribution of activators.
