چکیده

Rhodamine B dye-doped with titanium dioxide (TiO2) nanoparticles in certain proportions were prepared by simple sol-gel technique. The structural and morphological properties of the prepared samples were studied using X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The results showed that the TiO2 nanoparticles have spherical agglomerated shapes with anatase and rutile phases. The average crystallite size of the samples was calculated using the Debye-Schärer formula, ranging from (10 to 24) nm for anatase and rutile phases. The results show that when a percentage of Rhodamine is introduced, the crystallite diameter increases and the diameter ranges from (4 to 12) nm. The intensity of the peaks changes significantly and the phase is transformed by increasing the percentage of Rhodamine.
