Structural and optical properties of CdS nanocrystals embedded in NaCl single crystals

The elaboration of the CdS nanocrystals embedded in a NaCl single crystal has been performed using the Czochralski method. The optical density spectrum shows a blue shift of the absorption edge towards the high energies. The energy gap has been found to be 2.70 eV. The photoluminescence has been ass...

Description
Summary:The elaboration of the CdS nanocrystals embedded in a NaCl single crystal has been performed using the Czochralski method. The optical density spectrum shows a blue shift of the absorption edge towards the high energies. The energy gap has been found to be 2.70 eV. The photoluminescence has been assigned to the neutral-donor band (D 0, X) and radiative recombinations from deep defect and impurity levels.
