Abstract
Rb3V5O14, which was successfully synthesized by a water assisted solid state reaction (WASSR) method, is a fluorescent red pigment that is environmentally friendly. The Rb3V5O14 fluorescent pigment showed a strong optical absorption in the green light region due to the energy transfer from O2− 2p orbital to V5+ 3d orbital of VO5 polyhedra and band-gap energy of Rb3V5O14 was 2.02 eV. The fluorescent pigment presented a broad red emission peaked at 625 nm due to the 3T2 → 1A1 and 3T1 → 1A1 transitions of the [VO4]3− group. The Rb3V5O14 fluorescent pigment showed a bright-vivid red body color, and the L*, a*, and b* values were 47.4, +45.9, and +34.4, respectively.
