Self-assembly of tellurium nanorods

A simple solution phase approach is utilized to obtain tellurium microrod resulting from the self assembly of tellurium nanorod. The length of tellurium microrod can be tuned; manipulating the experimental condition the length of these rods can be made in centimeter range. Tellurium nanorods are synthesized by simple chemical recycling process, just reducing bulk Te powder by an aqueous solution of sodium dithionite and then oxidizing the solution in air to get Te nanorods. By controlling the airflow we can grow tellurium microrod by assembling these nanorods.
