TL;DRAbstract

Abstract Eu 3+ doped La 2 Ti 2 O 7 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 transmission electron microscopy (TEM) were employed to characterize the as‐synthesized nanoparticles. Furthermore, photoluminescence (PL) performances of the Eu 3+ doped La 2 Ti 2 O 7 nanocrystals were evaluated with focus on the effects of calcination temperature and Eu 3+ doping concentration on the photoluminescence properties.
