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 Scherrer's method and found to be in the range 20-25 nm. The effect of Eu3+ and Sm3+ cations on the luminescence properties of Mg2SiO4:RE3+ nanopart...
