Preparation and Characterization of Tellurium Nano-particles by Long Pulsed Laser Ablation

A long pulsed laser ablation with a moving target at high speed technique was applied to prepare tellurium nanoparticles from a tellurium target under argon gas at atmospheric pressure. The prepared nanoparticles were characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX), and Xray diffraction (XRD). The influence of the moving speed of the target on the size, morphology and crystallographic structure of the nanoparticles was investigeated. The results show that for the target moving at high speed without burning of the target the production of isolated nanoparticles is obtained. The diameter of the nanoparticles is ranging from 30 to 200 nm.
