The Hot-Injection Synthesis

Some of the early studies on the high-tech applications of semiconductor nanoparticles have been based on the above-mentioned preparative route, namely 

More recently, the dangerous organometallic precursors (especially dimethylcad-mium) have been replaced by les s dangerous cadmium compounds, such as CdO [99] or Cd-acetate [260], both of which can be dissolved inTOPO or ODE in the presence of carboxylic or phosphonic acids. This makes the high-temperature synthesis of nanocrystals in organic solvents much easier (and therefore accessible), without losing any of the excellent optical properties of the particles. 

Due to model limitations, however, departures of the theoretical curves from the experimental data were more pronounced at lower energies than for larger nanoparticles, which were more weakly confined.

Thiol stabilization also proved to offer a very successful route towards the creation of monosized nanoparticles of various compounds however, as it has also attracted widespread interest it will be outlined separately in Chapter 3.2.1.2. In this chapter, from this point onwards, attention will be focused on recent developments that differ from the hot injection synthesis and from the thiol technique.
