Light absorption in visible–NIR range by linear copper clusters (n = 2–22) with monoatomic thickness: a TD-DFT study

Autor: Natalia E. Markina, Ammar J. Al-Alwani, Alexey V. Markin, Alexander A. Skaptsov

Publikováno v: Journal of Nanoparticle Research. 22

The authors theoretically investigated absorbance spectra of the hypothetical 1D Cu clusters with 2–22 atoms and monoatomic thickness. In contrast to 3D isomers with interband transitions only ( 600 nm) compared to the nanoparticles with spherical
