| Abstract: | A novel CaAl2O4: Sm3+ (1 – 9 mol%) was synthesized by solution combustion method by using ODH as a fuel. The final product was well characterized by PXRD, DRS, SEM, TEM and PL. The PXRD profile of CaAl2O4:Sm3+ well matched with JCPDS NO.172155. The average crystallite sizes are found to be in the range 20 - 40 nm. From Diffuse Reflectance Spectra, the energy gap of the samples were calculated and found to be ∼ 2.6 - 3.1 eV. The PL emission peaks centered at ∼ 564, 601 and 647 |
