The preparation of phosphor material SrMgAl{sub 10}O{sub 17} with varying concentration of rare earth dopant Ce{sup 3+} synthesized by combustion method at 500°C. The synthesized phosphor material characterized for their crystal and nature by XRD measurements. The photoluminescence measurements of phosphor exhibit two PL spectra 389nm and 575 nm in blue and red region, respectively, this is due to crystal field and covalence effect. These results show that concentration quenching occur at 10mol%of Ce dopant. The results suggest the possibility of utilizing as a phosphor may be in solid state lighting.
