摘要：

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 466 nm light excitation, the CaTiO3:Eu3+ nanosheets showed a strong red (616 nm) emission corresponding to D-5(0)-> F-7(2) transition of Eu3+. The effect of Eu3+ concentration was investigated, among these samples, 0.2 mol% Eu(3+)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. (C) 2013 Elsevier B.V. All rights reserved.
