Abstract :
The effect of permanent hole burning is studied in the absorption spectra of quantum-sized CdS nanocrystals embedded in a polymeric film. The prolonged UV irradiation of CdS particles with mean diameter of about 3 nm and wide size distribution results in the formation of well-resolved dips with full-width of about 100–120 meV at room temperature. The selected photoexcitation of appropriate QS CdS nanocrystals is followed by their ionization and further irreversible oxidation of CdS phase by holes h+.
