In this paper that is experimental the purpose synthesis and characterization of CdS/ZnS quantum dot and study the effect of changes the shell on Properties their photophysical. The synthesis of the quantum dots can be produced wide spectrum. The synthesis of the quantum dots is chemical deposition method (reverse micelle). The colloidal quantum dots grow. Our purpose reviews effect shell size in the production spectrum white light using quantum dots. Using this spectrum can be Application of the quantum dots any of a variety of solar cells , biological and LED examined. and characterized of the quantum dots by the absorption, Fluorescence spectra , FT-IR, XRD,SEM.
