Abstract

A study was conducted to demonstrate a new simple two-step colloidal method to synthesize single-crystal PbTe nano-spheres and -rods with control of size and shape. Lead telluride was synthesized by the addition of an aqueous solution or suspension of a lead salt to a freshly prepared NaHTe solution. The solid product of this reaction was isolated by centrifugation, dispersed into TOP and injected into hot hexadecylamine (HDA) at temperatures of 190, 230, or 270 °C and held at the same temperature for 2 or 4 hours. The PbTe nanoparticles were isolated by the addition of methanol to the reaction mixture after being cooled to °C.
