Wet-Chemical Synthesis Basic Principles

A further critical contribution to the crystallization process is played by thermal energy and the way this is delivered in the solution (convective or dielectric heating) basically crystal nuclei can show different crystallographic phases, however their stability is firmly dependent on the temperature. It can happen that a solid material shows one crystalline phase at high temperatures and another one at lower. For instance, relatively to CdS elongated nanostructures Jun et al. reported a temperature-mediated phase control of the initial seeds finally producing nanorods for temperatures as high as 300°C and branched architectures for temperatures below 180°C [38, 39]. 

The selective effectiveness of dynamic surface interactions between NC crystallographic facets and solution-dispersed molecular ligands or gaseous particles will be successively detailed in the
