Description
Colloidal suspensions of PbTe nanoparticles coated with oleic acid were obtained using a high-temperature solution phase method. Diphenyl ether was used as a high-boiling heat-transfer agent. Nanoparticle size was tuned during the synthesis by means of reaction temperature. The reaction temperature was varied between 140 degrees Celsius and 200 degrees Celsius, and the trioctylphosphine - Te/lead oleate molar ratio was selected as 2 : 1. High resolution transmission electron microscopy and powder X-ray diffraction were used to characterize the size, shape, structure, and composition of the PbTe nanocrystals. Ordering of nanocrystals into a close-packed structure indicates that the PbTe nanoparticles have a well-defined shape and a narrow size distribution. (authors)
