Evidence of progressive Fe2+ to Fe3+oxidation in Fe2+-doped ZnO nanoparticles
When Fe-ions enter into the ZnO NPs, their oxidation state can be tuned and the excitonic peak enlarges, indicating that the ZnO lattice becomes more disordered. The AFM interactions found in paramagnetic NPs become stronger as Fe content increases.
