Abstract
$Sr_xBa_{(1-x)}TiO_3$ red phosphors doped with Pr(0.13 mol%) and Al(O.23 mol%) were synthesized by solid state reaction method. Orthorhombic perovskite structure with increasing value of x in $Sr_xBa_{(1-x)}TiO_3$:Pr,Al phosphors changed to cubic perovskite structure. Emission bands at 615 nm and 492 nm in $Sr_{0.25}Ba_{0.75}TiO_3$:Pr,Al and $BaTiO_3$:Pr,Al phosphors were observed at room temperature. The main cause of green luminescence at 492 nm was explained by the change of the 4f5d band.
