Abstract

The synthesis of hexadecylamine capped (HDA) CdTe and PbTe via a simple hybrid solution based high temperature route is described. In this method the tellurium is first reduced to form the telluride salt followed by reaction with the metal salt and finally thermolysis in a coordinating solvent. The metal salt and reaction temperature played an important role in the morphology and growth mechanism of the particles. The CdTe particles where in the form of rods and spheres whereas the PbTe nanoparticles were in the form of nanowires. The oriented attachment mechanism is proposed for the growth of elongated particles under certain reaction conditions.
