摘要：

Bismuth telluride (Bi-2,Te-3) nanoparticles were prepared by laser ablation in the presence and absence of protective agents. Addition of protective agents could decrease the size of particles, and improve the particle size distribution as well as the colloidal dispersion stability. XRD and HR-TEM have clarified that the Bi2Te3 nanoparticles, thus prepared, have a rhombohedral structure.
