Synthesis, micro-structural, and electrical analysis on lanthanum fluoride

Lanthanum fluoride nanorod and nanoparticles have been synthesized by a simple method with and without sonication, respectively. Thermogravimetric/differential thermal analysis confirms the sample formation at low temperature for the sonication-assisted sample than the directly prepared sample. The structure of the prepared lanthanum fluoride nanorods and nanoparticles has been analyzed by X-ray diffraction studies and the micro-structural properties have been studied using transmission electron microscopy. The transmission electron microscopic image reveals a capsule-like shape for the sample prepared under sonication. Ion conduction and conductivity analysis of the prepared nanorods and nanoparticles has been studied using AC impedance spectroscopy, and the ionic conductivity was found to increase by an order for the sample prepared with sonication.
