ABSTRACT = {Ba<sub>0.7</sub>Sr<sub>0.3</sub>TiO<sub>3</sub>:Sm<sup>3+</sup>
 modified K<sub>x</sub>Na(<sub>1-x</sub>)NbO<sub>3</sub> ceramics with perovskite-type structure were 
synthesized via solid state sintering method. Sm<sup>3+</sup>
 ions doping was designed for 
substituting both A and B sites in the ABO3 structure, Sm<sup>3+</sup>
 doped Ba<sub>0.7</sub>Sr<sub>0.3</sub>TiO<sub>3</sub>
(Ba<sub>0.7</sub>Sr<sub>0.3</sub>TiO<sub>3</sub>:Sm<sup>3+</sup>
) oxide precursor powders with the chemical formula of 
Ba<sub>0.7</sub>Sr<sub>0.3x</sub>Sm<sub>x</sub>(Ti<sub>1-x</sub>Sm<sub>x</sub>)O<sub>3</sub> (x=0.005, 0.015, 0.025) were synthesized. Combined 
Ba<sub>0.7</sub>Sr<sub>0.3</sub>TiO<sub>3</sub>:Sm<sup>3+</sup>
 with K<sub>0.5</sub>Na<sub>0.5</sub>NbO<sub>3</sub>, the perovskite-type solid solution composite 
ceramics were fabricated via solid phase sintering method. X-Ray diffraction was used for 
investigating the phase structure of the precursor powders and luminescent composite 
ceramics. The photoluminescence properties of the Sm<sup>3+</sup>
 ions in the 
Ba<sub>0.7</sub>Sr<sub>0.3</sub>TiO<sub>3</sub>-K<sub>0.5</sub>Na<sub>0.5</sub>NbO<sub>3</sub> composite ceramic materials were systematically 
investigated by exploring the effects of composition of the composites, excitation 
wavelength and temperature on photoluminescence. },
