Controlled Synthesis of Lead Telluride Nanocrystals

Abstract:

Nanocrystalline PbTe particles of controlled size and shape are synthesized via chemical route at different growth temperatures. The size of the nanoparticles is in the range ~ 20 to 35 nm. The size and shape of the particles have been controlled by controlling temperature, using proper surfactant and maintaining the atomic ratio between Pb and Te. The intrinsic properties of surface energy of different crystallographic planes involve in growth process are studied. The crystallinity and phase of PbTe nanocrystals are analyzed by X-ray diffraction (XRD). The shape and size of the nanocrystals have been characterized by transmission electron microscopy (TEM). The optical band gap of nanocrystals is determined by FTIR photo-absorption spectra.
