This paper reports the photoluminescence and nonlinear optical (NLO) properties of Ce₂O₃-TiO₂ nanocomposites synthesized via sol-gel process with different concentrations of cerium. The physical characterization studies by means of XRD indicated for the successful incorporation of Ce into the lattice of TiO₂, while the UV-visible spectra for an absorption edge shift of TiO₂ to the higher wavelength side following the Ce addition, and FESEM analysis for the morphology and particles sizes of the synthesized materials. On testing of the photoluminescence properties recorded through time-resolved fluorescence (TCSPC) technique, a decrease in the intensity of TiO₂ with that of increased Ce concentration was observed and is due to an escalation in the number of oxygen vacancies. Further, the observation NLO properties for Ce₂O₃-TiO₂ was done by a |
