Solvothermal synthesis of lead telluride micro- and nanocrystals

Single-crystalline nanoparticles and rod-shaped lead telluride microparticles were obtained using solvothermal synthesis. It is shown that the reaction temperature, time of the synthesis, and precursor molar ratio make it possible to tune the shape and size of nanocrystals. X-Ray powder diffraction with transmission electron microscopy was used to confirm the crystallinity and morphology of nanoparticles obtained. The temperature dependence of the electric conductivity was also measured, and its values are close to values of bulk PbTe.
