Figure 2: (a) XRD patterns of undoped and Ga-doped TiO2 nanoparticles. (b) Magnified XRD graph of the undoped TiO2 sample between 36° and 40° of 2θ values, showing the resolution of (103), (004), and (112) peaks after deconvolution. (c) Magnified (101) peaks of the undoped and Ga-doped TiO2 nanoparticles showing the strain broadening effect within the doped samples. (d) Size-strain analyses of undoped and Ga-doped TiO2 nanoparticles.
