Abstract: Colloidal CdSe/CdSe1-xSx heterostructure nanorods were synthesized by the seeded growth method. By changing the temperature, type of ligand, we synthesized the Wz-CdSe nanocrystals as seeds for growth of CdSe/CdSe1-xSx heterostructure nanorods. The yield of heterostructure nanorods depend on the amount of oleylamine in the reaction mixture. Their morphology, crystalline structure and optical properties were investigated by transmission electron microscopy, X-ray diffraction, optical absorption and photoluminescence spectroscopy.

Keywords: heterostructure nanorods, oleylamine, photoluminescence.
