Abstract For the first time we report on, structural, electrochemical, optical and electron paramagnetic resonance (EPR) properties of Mg2SiO4:Fe3+ nanomaterial synthesized by low temperature (350 °C) solution combustion method. Cyclic voltammetry and electrochemical impedance analysis were carried out to investigate the conduction efficiency and charge transfer resistance of Fe3+ doped Mg2SiO4. The Kubelka–Munk theory was used to calculate the bandgap of the prepared nanomaterial by analysing the diffuse reflectance spectra. Photoluminescence properties were studied by exciting the samples at 375 nm wavelength which results in yellow emission and applicable for warm white light emitting devices. The quantum efficiency of the optimized sample was found to be 46%. The decay curve analysis were carried out for the optimized (3 mol%) sample was found to be 6.4 ms. The EPR spectra were recorded at RT in X-band for Fe3+ (1 & 11 mol%) doped Mg2SiO4.
