Sodium dodecyl sulfate-assisted synthesis of CoWO4 nanorods
Source abstract
Abstract
CoWO4 nanorods were synthesized at 453 K for 12 h by a hydrothermal technology from Na2WO4 · 2H2O and CoCl2 · 6H2O in the presence of sodium dodecyl sulfate (SDS). The as-synthesized CoWO4 nanorods were characterized by various techniques of X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and X-ray detector. Luminescent properties of the samples were measured at room temperature. The results showed that CoWO4 products are nanorods with diameters of about 20 nm, and lengths ranging between 100 and 200 nm. CoWO4 nanorods display a very strong PL peak at 453 nm with the excitation wavelength 300 nm. The possible formation mechanism of CoWO4 nanorods was suggested.
