| Abstract
| - Tetrapod-shaped CdSe nanocrystals have been successfully synthesized in high yields using a simplemethod of controlling the protonic acidity of the reaction system. A possible growth mechanism is discussedon the basis of the surface modification of H+ present. The crystal structure of CdSe tetrapods is determinedby high-resolution transmission electron microscopy analysis to have a zinc blende core at the centerwith four wurtzite arms growing out from the core along four [111] directions. The electronic structureof CdSe tetrapods is studied theoretically in comparison with that of spherical dots.
- Tetrapod-shaped CdSe nanocrystals have been successfully synthesized in high yields (about 80%) by controlling the protonic acidic circumstance in the OA−TOP reaction system. The core diameter, the arm width, and the arm length are estimated to be about 4, 3, and 8 nm, respectively.
