Flower-like Se nanorods synthesized via carbamide-assisted hydrothermal routes

Flower-like Se nanostructures consisting of clusters of nanorods with width of 40–100 nm and length of several 100 nm have been synthesized via a carbamide-assisted hydrothermal method. The optimal clusters are composed of nanorods protruding from a central point. FESEM and TEM demonstrate the flower-like morphology. The X-ray diffraction (XRD) pattern shows that the as-prepared flower-like Se nanostructures are of hexagonal phase.
