“…[15] Selenium has been widely used in the field of solar cells, rectifiers, and xerography. [16,17] Recently, several approaches have been employed to prepare selenium nanostructures with controllable morphologies. Typically, selenium nanoparticles are synthesized by reducing a selenious acid solution with ascorbic acid in the presence of polysaccharides, [18] or prepared by pulsed laser deposition (PLD) using a YAG laser with a power of 532 nm.…”

Selenium nanoparticles and nanorods were successfully prepared in a mixed solvent of ethylene glycol and water at a relatively low temperature of 85°C. No other surfactant or template was employed, and glucose was used as a green and mild reducing reagent in the current synthesis. The volume ratio of ethylene glycol to water played an important role for controlling the shapes of selenium products. The obtained selenium samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), Raman spectra, and UV-vis absorption spectra. The evolution process from amorphous selenium to a trigonal phase complied with a "solid-solution-solid" formation mechanism. HRTEM and SAED results indicate that the trigonal selenium nanorods grow along the [001] direction. This method might provide an environmentally-friendly and low cost route for the synthesis of other related nanomaterials with controlled morphologies.

Selenium (Se) nanowires were grown in the pores of anodic alumina membrane as template. Facile electrodeposition technique was used for the synthesis of Se nanowires. Scanning electron microscopy was used for the morphological study of the nanowires. X-ray diffraction and Energy dispersive X-ray fluorescence were utilised for the structural characterisation. The optical properties of Se nanowires were investigated using optical absorption spectroscopy.
