Heterogeneity in iron-doped titania flower-like nanocrystalline aggregates: detection of brookite and anatase/rutile size-strain modeling

Detailed investigations of Raman spectra and X-ray powder diffraction patterns of rutile-rich and anatase/brookite-poor flower-like nanocrystalline aggregates of Fe-doped TiO₂ shed new light with regard to its microstructure and heterogeneity.
