Solvothermal growth and characterization of one-dimensional-nanostructured materials NH4LnF4 and LnF3 (Ln=Nd, Sm, Eu, Gd and Tb)

High-yield one-dimensional (1D)-nanostructured NH4LnF4 (Ln=Nd, Sm, Eu, Gd and Tb) were grown by template-free solvothermal approach at 150 °C. X-ray diffraction, transmission electron microscopy (TEM) and high transmission electron microscopy (HRTEM), Fourier transform infrared spectroscopy (FT-IR), photoluminescence spectra, and thermogravimetric and differential thermal analysis (TG-DTA) have been employed to characterize the products. The 1D-nanostructured LnF3 (Ln=Nd, Sm, Eu, Gd and Tb) can be obtained by calcination corresponding to 1D-nanostructured NH4LnF4. The possible growth mechanism of 1D-structured NH4LnF4 (Ln=Nd, Sm, Eu, Gd and Tb) was discussed.
