摘要：
The formation of gold and silver nanoparticles during laser ablation of metal targets in aqueous solutions of amino acids (L- and D-methionines and L-cysteine) and β-cyclodextrin is experimentally investigated. A nanosecond ytterbium-doped fiber laser is used as a radiation source. Colloidal solutions of nanoparticles are investigated by optical spectroscopy, high-resolution transmission electron microscopy, and circular dichroism spectroscopy. Induced Cotton effects at plasmon resonance frequencies are found in the circular dichroism spectra of the nanoparticles generated in a β-cyclodextrin solution. These effects are due to the interaction of ligand with nanoparticles.
