Its microstructure and micromorphology have been analyzed by x-ray powder diffraction and scanning electronic microscopy, which indicates that there exist some novel cobblestone-like microcrystalline particles. With Pb2+ as a sensitizer, these materials all exhibit strong red emission near 618 nm due to the 5 D 0 → 7 F 2 transition of Eu3+ ions. At x=1.5, YVO4:Pb2+, Eu3+ shows the strongest emission intensity, which indicates an efficient energy transfer from Pb2+ to Eu3+.
