The Rietveld profile fitting of X-ray diffraction pattern of pure anatase TiO2 NPs. Experimental (symbols) and fitting (solid lines) X-ray diffraction patterns. The positions of Bragg reflections are denoted by vertical bars. The difference (experiment minus calculation) curve is shown by a solid line at the bottom.
