Abstract : Bismuth selenide (Bi2Se3) nanotubes have been synthesized for the first time using dimethyl formamide (DMF) by solvothermal method. Ammonium bismuth citrate (C24H20Bi14O28,6NH3,10H2O), elemental selenium (Se) and {DMF} when treated solvothermally in an autoclave at 165 °C formed Bi2Se3 nanocrystals of different morphologies. The morphological modifications are found to depend on the duration of heat treatment and the relative proportions of the reactants. Heat treatment for 24 h yields Bi2Se3 nanotubes whereas large needle shaped structures are produced on altering the relative proportions of the reactants during the same period. The as synthesized products were characterized by XRD, {EDXA} and TEM.
