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.
