Abstract |
PbTe nanostructures were prepared by a hydrothermal method on presence of different surfactant. Results show that in constant condition by changing the capping agent the morphology of as-obtained PbTe were revolutionize PbTe nanostructures show a strong photoluminescence peak at 402 nm at room temperature, also optical absorption spectrum of PbTe nanostructures exhibit an extreme blue-shift, which is attributed to the quantum confinement of charge carriers in the nanostructures. X-ray diffraction, scanning electron microscopy, transmission electron microscopy, photoluminescence spectroscopy, and Fourier transformed infrared spectroscopy were used to characterize the as-produced PbTe nanostructures. |
