摘要：
Uniform cubic-shaped PbTe and PbSe nanocrystals have been synthesized through the surfactant-assisted hydrothermal reaction between Pb(NO3)(2) and Te or Se powders with hydrazine hydrate as reducing reagent. The products were characterized by powder x-ray diffraction (XRD) and transmission electron microscopy (TEM). It was found that the shapes of nanocubes are well controlled by using ethylenediaminetetraacetic acid as chelating reagent and in the presence of poly(vinyl-pyrrolidone).
