Abstract
Hollow cadmium selenide (CdSe) tetrapods were synthesized on a large scale. The directional growth of twins led the tetrapod nanostructure to be formed. The silicon powder was responsible for the growth of the hollow tetrapods. The UV-visible absorption spectra of the hollow CdSe tetrapods display an absorption edge at about 765nm. There is a redshift of 53nm of the absorption edge, in comparison with that of bulk CdSe at 712nm. In the Raman spectra, two new anomalous modes at 250.91 and 493.42cm−1 are observed. This might originate from the enhanced internal stress of hollow structures.
