摘要
Control of size and shape: The high-yield chemical synthesis of size-selected CdSe tetrapods (see microstructure pictures) is presented. This method is based on nucleation of nanodots with a zinc-blende lattice structure and growth of the arms with a wurtzite structure on the four [111] facets of the dots. Absorption, emission and photoluminescence excitation spectra are presented and discussed. (Figure Presented). © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
