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. date: 2013 date_type: published publisher: VNU official_url: https://js.vnu.edu.vn/MaP/article/view/861 contact_email: luyen0803@gmail.com full_text_status: public publication: VNU Journal of Science, Mathematics - Physics volume: 29 number: 2 pagerange: 40-47 refereed: TRUE issn: 2588-1124 referencetext: [1] L.
