Chemical bath deposition of CdSe and CdS nanocrystalline films: tailoring of morphology, optical properties and carrier dynamics

We review the results of our research towards tailoring morphology and optical properties of films consisting of closely‐spaced nanocrystals of CdSe and CdS whose optical band‐gap can be tuned to cover the whole visible spectral range. On basis of the obtained results, in particular of photoexcited...

description We review the results of our research towards tailoring morphology and optical properties of films consisting of closely‐spaced nanocrystals of CdSe and CdS whose optical band‐gap can be tuned to cover the whole visible spectral range. On basis of the obtained results, in particular of photoexcited carrier dynamics, we have proposed a microscopic model that describes well the optical properties of the films. We have also showed that the spin relaxation of electrons in these nanocrystalline films is different than that in mutually isolated nanocrystals of the same size. (© 2008 WILEY‐VCH Verlag GmbH & Co.
