Nontoxic fluorescent red pigment Rb3V5O14 was synthesized by WASSR method.
Rb3V5O14 exhibited a broad red emission with a peak at 625 nm.
The fluorescent pigment has a strong optical absorption band in the green light region.
The fluorescent pigment obtained in this study shows the bright-vivid red body color.
The Rb3V5O14 fluorescent red pigment is expected for application as the color cosmetics.
