Abstract	A reduction-carbonization approach for the formation of one-dimensional (1D) silver telluride nanocables and tellurium nanorods with a sheath of amorphous carbon are proposed. Here the carbon shell is obtained with the assistance of glucose which behaves as carbonizing agent; silver nitrate and sodium tellurite are utilized as precursors and ethylene glycol acts as reducing agent. The results demonstrate the Ag$_{2}$Te/C and Te/C nanostructures with average diameters of 150 and 100 nm, respectively. The crystal structures, morphology, and composition are studied using X-ray diffraction, scanning electron microscopy, high-resolution transmission electron microscopy, and Energy-dispersive X-ray spectroscopy characterizations. The formation mechanism of amorphous carbon sheath and finally core–shell nanostructures is elaborated on the basis of the experimental results. In addition, nonlinear absorption and refraction coefficients along with 3rd order nonlinear optical properties are investigated by open/closed-aperture Z-scan measurements using femtosecond pulse laser at 800 nm in a systematic way. This study provides a guide to the nonlinear properties, which may hold promise as advanced materials for various applications.
