Characterization of CdS quantum dots prepared by a chemical method

الملخص EN

The CdS quantum dots were prepared by chemical reaction of cadmium oleylamine (Cd-oleylamine complex) with the sulfite-oleylamine (S-oleylamine) with 1:6 mole ratios.

The optical properties structure and spectroscopy of the product quantum dot were studied.

The results show the dependence of the optical properties on the crystal dimension and the formation of the trap states in the energy band gap.
