Paper Abstract

The effect of permanent hole burning is studied in absorption spectra of quantum sized CdS nanocrystals with the mean diameter of about 30 angstroms and wide size distribution embedded in polymeric film. The selective photoexcitation of appropriate CdS quantum dots followed by their ionization and further irreversible oxidation of CdS phase by holes h+ is considered to be responsible for this effect.
