Abstract
We report structural, optical and magnetic behavior of polyvinylpyrrolidone (PVP) capped iron containing tin dioxide (SnO2) nanoparticles synthesized via facile cost effective, environmentally benign, low temperature hydrothermal process. X-ray diffraction pattern of pristine SnO2 revealed the formation of tetragonal rutile phase with lattice parameter, a = 0.479 nm, c = 0.323 nm; crystallite size being about 3 nm. The incorporation of iron resulted in progressive increase of unit cell parameters and average crystallite size, despite the fact that Fe3+ ion has lower ionic radius than Sn4+. The high resolution electron micrographs revealed the [110] preferred crystal orientation.
