摘要：

The improvement of the optical properties of Titanium dioxide by doping with transition metals and rare earth ions is one of the most studies carried out by researchers. In this paper the TiO2: 0,01 Mn2+ x Ce3+ (x= 0; 1; 2 and 5 mol%) was synthesized by co-precipitation way. The structural and morphological properties were defined using X-ray diffraction, Fourier Transformation Total Infrared Reflection (FTIR), Raman Spectroscopy and Scanning Electron Microscopy coupled with Energy Dispersive X-ray (SEM/EDX). The optical properties have been studied by UV-Visible spectroscopy. The co-doping with Ce3+ affects the lattice parameters of TiO2 and decreases the optical gap energy Eg which improve the absorption capability in the UV-Visible region. The results are discussed.
