Abstract

$M(WO_4)$:Eu phosphor as a red emitting phosphor for LED was prepared by solid state method. Tungstate phosphors were exited at long wavelength ultra violet region. In special, the emission of Eu-doped $M(WO_4)$:Eu phosphor under the excitation of 410nm appeared at 613nm. $M(WO_4)$:Eu phosphors with M : Group 1 had a higher excitation intensity than those of the phosphors with M: Group 2 at long-wavelength UV.
