Synthesis of Neodymium Hydroxide Nanotubes and Nanorods by Soft Chemical Process
A facile soft chemical approach using cetyltrimethylammonium bromide (CTAB) as template is successfully designed for synthesis of neodymium hydroxide nanotubes. These nanotubes have an average outer diameter around 20 nm, inner diameter around 2 nm, and length ranging from 100 to 120 nm, high BET surface area of 495.71 m2 g−1. We also find that neodymium hydroxide nanorods would be obtained when CTAB absented in reaction system. The Nd(OH)3 nanorods might act as precursors that are converted into Nd2O3 nanorods through dehydration at 550 °C. The nanorods could exhibit upconversion emission characteristic under excitation of 591 nm at room temperature.
