Abstract:The optical and luminescent properties of nanostructures of CdS / ZnS QDs and CdS QDs doped with lithium, obtained by the sol-gel technology in an aqueous solution of gelatin, have been studied. It was determined from the optical absorption spectra of the CdS / ZnS QD nanostructures that the thickness of the shell layer corresponds to the thickness of one ZnS monolayer. The luminescence spectra revealed a significant increase in the intensity of luminescence nanostructure. The absorption spectra of undoped and… Show more
