Abstract
A convenient solvothermal reduction pathway to Bi2Te3, Bi4Te3 and Bi2Se3 na nocrystals has been developed by the reactions between bismuth nitrate and tellurium in various solvents in the presence of hydrazine hydrate or white phosphorus as reducing agent. The products were characterized by X-ray pow der diffraction and transmission electron microscopy. The influence of solv ents and temperature on the reactions was investigated.
