Summary, etc. <p class="Normal1">The CeO<sub>2</sub>-TiO<sub>2</sub> nanoparticles were prepared by a combination of hydrothermal and sol-gel preparation methods. the bond structures and crystal properties of the obtained materials were featured with X-ray diffraction, FTIR, Raman, and Bet analysis; surface morphologies were examined with the help of FESEM and STEM. And finally, the PL properties of the synthesized samples were also examined in this study. The excitation and emission spectra of 0.1 mol% and 0.25 mol% CeO<sub>2</sub> doped TiO<sub>2</sub> phosphors consist of broad bands in the UV (200–300 nm) region with maxima at 254 nm. The excitation band at 254 nm is defined as the charge transfer band (CTB). In the emission spectra, a broadband located from 400 to 700 nm is related to the 5d-4f (5d1→4f1) transition of Ce<sup>3+</sup> in TiO<sub>2</sub>. According to the PL result, the 5d–4f transition of Ce<sup>3+</sup> is heavily dependent on the concentration of Ce<sup>3+</sup> in the host crystal TiO<sub>2</sub>.</p>
