The reactions used for synthesis of II-VI (CdSe, CdTe), III-V (InP, InAs), and IV-VI (PbS, PbSe, PbTe) semiconductor nanocrystals are outlined by Schemes 3-5.4,17,30-32 The syntheses are carried out at high temperatures, and in the presence of long-chain alkylphosphines (trioctylphosphine,TOP), alkyl-phosphine oxides (trioctylphosphine oxide, TOPO), alkylamines (hexadecyl-amine, HD A), and alkylphosphonic acids as the stabilizing agents. 

Colloidal semiconductor nanocrystals are attracting growing attention as the building blocks for inexpensive, large-area, solution-processed solar cells. The advantages here are the scalable and controlled synthesis, an ability to be processed in solution, the broadband absorption, and the superior transport properties of traditional photovoltaic semiconductors. Solar cells that rely exclusively on colloidal nanocrystals have been anticipated theoretically58 and...

The body of work presented in this chapter has focused largely on the synthesis of colloidal doped semiconductor nanocrystals, and on the application of a wide variety of characterization techniques to ensure dopant incorporation into the host semiconductor lattice.

In brief, the test proposed by Bol et al. (2002) to determine whether the lanthanide ion is incorporated in a semiconductor lattice has to be used with care. A detailed analysis of the energy levels and phonon spectrum may present additional information. In our opinion, it is possible to incorporate the lanthanide ions into lattice sites of semiconductor nanocrystals (e.g., II-VI) if the synthesis method is well designed and the charge-imbalance is compensated. 

Quantum dots represent three-dimensional confinement in semiconductor materials. The optical spectroscopy of lanthanides-doped III-V semiconductor QDs has been observed to be very different from the bulk or thick film. For example, carrier confinement in QDs can strongly enhance the radiative quantum efficiency of the lanthanide emission, which thus makes lanthanide-doped III-V semiconductor QDs very promising candidates for full-color LEDs. It is notoriously difficult to dope lanthanide into III-V semiconductor nanocrystals by wet chemical synthesis methods. To date, most of these samples were prepared either by MBE, ion implantation or magnetron co-sputtering. 

From a practical point of view, nanotechnology and nanosciences started in the early 1980s. Major developments were the birth of cluster science, the development of the scanning tunneling microscope, the discovery of buck-minsterfullerene (the C60 buckyball) and carbon nanotubes, as well as the synthesis of semiconductor nanocrystals, which led to the development of quantum dots [4].
