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 1000ºC 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 for Sm3+ . The emission spectrum of Sr3B2O6:Sm3+ exhibited four sharp emission peaks corresponding to4G5/2®6H5/ 2 (563-572 nm),4G5/2®6H7/ 2 (598-614 nm),4G5/ 2 ®6H9/2 (647-666 nm), and4G5/ 2 ®6H11/ 2 (705 - 714 nm) transitions of Sm3+ . The relation between the charge transfer band of Sm3+ ion and the host composition was discussed.
