摘 要：Eu3+ doped La2Ti2O7 nanocrystals with pure monoclinic phase and size of about 100 nm were prepared by a citric acid（CA） assisted sol-gel method.Techniques of thermo-gravimetric（TG） and differential scanning calorimetry（DSC） ,X-ray diffraction（XRD） ,as well as transmis-sion electron microscopy（TEM） were employed to characterize the as-synthesized nanoparticles.Furthermore,photoluminescence（PL） performances of the Eu3+ doped La2Ti2O7 nanocrystals were evaluated with focus on the effects of calcination temperature and Eu3+ doping concentration on the photoluminescence properties.
