A simple and low-cost solution combustion method was used to prepare Eu3+and Sm3+ (1-11 mol%) doped Mg2SiO4 nanophosphors at 350 oC using metal nitrates as precursors and ODH as fuel. The final products were well characterized by Powder X-ray Diffraction, Fourier Transform Infrared spectroscopy, scanning electron microscopy and DRS. The PXRD patterns of the as-formed products show single orthorhombic phase. The crystallite size was estimated using...
