A simple microwave-assisted hydrothermal synthesis of lanthanum hydroxide nanowires with a high aspect ratio

Uniform La(OH) 3 nanowires (NWs) with a high aspect ratio of more than 200 have been successfully synthesized by a simple microwave-assisted hydrothermal (MH) process. Comparing to a conventional hydrothermal (CH) one, the La (OH) 3 powders obtained are nanorods in shape with an aspect ratio below 1...
