摘要
For the first time the synthesis of of Yb metal nanoparticles is reported. The synthesis was made using the bioreduction methods. By the change in the pH the nanoparticles of 2 up to 10 nm were obtained. Size and structure determination was made using low magnification and high resolution transmission electron microscopy, which demonstrated that the particles are mainly of fcc-like structures. Theoretical calculations for by of molecular dynamics simulation for configurations with 4000 atoms of the Yb nanoparticle demonstrated that the fcc-like structure is the lowest energy configuration.
