Abstract
Hexagonal CaTiO3:Eu3+ nanosheets were prepared by a supercritical fluid method. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM) and luminescence spectrometer (LS). Under 466Â nm light excitation, the CaTiO3:Eu3+ nanosheets showed a strong red (616Â nm) emission corresponding to 5D0â7F2 transition of Eu3+. The effect of Eu3+ concentration was investigated, among these samples, 0.2Â mol% Eu3+doped CaTiO3 nanosheets showed the strongest luminescent intensity. Compared with nanoparticles, the nanosheets showed better luminescence property. Growth mechanism of hexagonal CaTiO3 nanosheets was also discussed.
