A NOVEL REDDISH ORANGE LUMINESCENT MATERIAL Sr3B2O6:Sm3+

Abstract

The Sm3+ doped Sr3B2O6 phosphors were synthesized using a solution combustion synthesis method followed by heating of the precursor combustion ash at 1000 degrees C in air. The synthesized phosphors were characterized by powder XRD. The photoluminescence properties of Sm3+-doped Sr3B2O6 were investigated at room temperature. The photoluminescence spectra at room temperature show the f-f transitions typical of Sm3+ . The emission spectrum of Sr3B2O6: Sm3+ exhibited four sharp emission peaks corresponding to (4)G(5/2) -> H-6(5/2) (563-572 nm), (4)G(5/2)( )->( ) H-6(7/2) (598-614 nm), (4)G(5/2 )-> H-6(9/2) (647-666 nm), and (4)G(5/2) -> H-6(11)/2( )(705-714 nm) transitions of Sm3+. The relation between the charge transfer band of Sm3+ ion and the host composition was discussed.
