Abstract

The structural and optical properties on $Bi^{3+}$ addition in (Y,Gd)(V,P)$O_4:Eu^{3+}$ red phosphor were investigated. With the addition of $Bi^{3+}$, the band edge in excitation spectrum shifts toward longer wavelength region, resulting in remarkable enhancement of the red emission intensity at 619 nm.
