Ferromagnetic and Photoluminescence Properties of Fe doped Indium-Tin-Oxide Nanoparticles Synthesised by Solid State Reaction

Iron and tin codoped indium oxide (In0.90Sn0.05Fe0.05)2O3) nanoparticles were synthesized by solid state reaction. The synthesized nanoparticles were studied for their structural, surface, chemical, optical, magnetic and photoluminescence properties using respective characterization techniques. The XRD and FE-SEM images confirmed the nanosize of the particles. Raman studies indicated no structural changes in the indium oxide lattice after addition of Fe and Sn into the lattice. From magnetic studies it was observed that the Sn doped indium oxide nanoparticles were ferromagnetic. The ferromagnetic nature is destroyed after codoping of iron and tin in indium oxide lattice. Two broad emission peaks were observed in photoluminescence spectra.
