| Abstract
| - Highly homogeneous and luminescent CdSe colloidal nanocrystals in the less common zinc blende crystalstructure have been obtained at high temperature in a noncoordinating organic solvent. The key parameterappears to be the addition of a phosphonic acid to the trioctylphosphine−selenium complex before its injectioninto the hot cadmium mixture, while the role of temperature is less relevant. Compared to standard (wurtzite)colloidal CdSe preparations, we find that the growth rate is considerably reduced, and the energy gap betweenthe first two absorption bands becomes larger.
