抄録

A large number of CdSe nanorod-assembled microtubes are prepared via a hydrothermal method in an ethanolamine–PEG solution. The tubes with inner diameters of 900 nm and lengths of 5–50 μm are composed of well-aligned nanorods around 300-nm long. It was found that both the solvent ethanolamine and surfactant PEG-20000 play a key role in the formation of nanorod-assembled microtubes. Ethanolamine as a mild reducing agent was used to reduce SeO<SUB>2</SUB> to produce Se<SUP>2−</SUP>. The optimal conditions to produce CdSe microtubes are that the volume ratio of ethanolamine to water is 1:4 and that the quantity of PEG is 3.0 g. The possible formation mechanism of CdSe microtubes is also discussed.
