Abstract

Abstract: Magnesium metavanadate dihydrate (MgV2 O6 ·2H2 O) was synthesized as a nanophosphor by a water-assisted solid-state reaction (WASSR) method, and its crystal structure and luminescence properties were investigated in detail. MgV2 O6 ·2H2 O has an orthorhombic structure with space group Pnma . In the crystal structure, the MgO6 octahedra and VO4 tetrahedra formed a layered structure in the direction of the b axis, and the VO4 tetrahedra formed a chain structure along the a axis. The nanophosphor showed broad and strong optical absorption in the near-ultraviolet region and exhibited a broad yellow emission peak at 563 nm. Highlights: MgV2 O6 ·2H2 O nano-phosphor was synthesized by a water assisted solid state reaction method. Their precise crystal structure and photoluminescence properties were investigated in detail. MgV2 O6 ·2H2 O has orthorhombic structure with a space group of Pnma. The nano-phosphor exhibited the broad yellow emission with a peak at 563 nm.
