Synthesis and characterization of MgF2 and KMgF3 nanorods

MgF2 nanorods with diameters of 60-100 nm were synthesized by a microemulsion method. Subsequent hydrothermal reaction of as-synthesized MgF2 nanorods and KF at 240degreesC for 3 days or 140degreesC for 7 days resulted in KMgF3 nanorods, which retained the rod-like morphology of the source material MgF2 in the reaction process. The morphology of as-synthesized MgF2 strongly depended on the molar ratio between water and the surfactant CTAB and the concentration of CTAB. (C) 2004 Elsevier Inc. All rights reserved.
