WebApr 13, 2024 · CdSe quantum dots stabilized with oleic acid were obtained by the colloidal method and their optical properties were studied. The average nanoparticle size, determined by the exciton absorption peak, was 3.7 nm. By growing a ZnS shell onto the surface of CdSe nanoparticles, CdSe/ZnS core-shell hybrids are synthesized. In this case, the … The CdSe ligand shell may contain both X type ligands which form covalent bonds with the metal and L type ligands that form dative bonds. It has been shown that these ligands can undergo exchange with other ligands. Examples of X type ligands that have been studied in the context of CdSe nanocrystal surface … See more Cadmium selenide is an inorganic compound with the formula CdSe.
