Hydrothermal Synthesis of EuF3 Nanorods

EuF3nanorods with 400 nm in average diameter and 950 nm in length have been synthesized via a hydrothermal method at low temperature. The phase and shape of the products were characterized by XRD, SEM, HRTEM and SAED. Studies show that the chelating agent EDTA is vital to the morphology of the final product. Under longer UV excitation, the as-prepared EuF3nanorods emitted the yellow and red light. This method will find its applications in exploring the crystal growth process and provide guidance for the morphology controllable synthesis.
