Hydrothermal synthesis of CoSe nanostructures without using surfactant

CoSe nanostructures are synthesized by hydrothermal route in the presence of reductant, without using surfactant. In this work, we use from SeCl4 as a new selenium source. By varying the type of metal salt and reductant, reaction time and temperature, the method permits us to synthesize products with different morphologies. SEM and TEM images show the morphology and size of the as-synthesized samples. Chemical composition of the samples is characterized by XRD and EDS. Magnetization measurement shows paramagnetic behavior for CoSe nanostructures.
