Formation and absorption spectrum of copper nanoparticles from the radiolytic reduction of Cu(CN)2-

Article Abstract:

A new study uses monovalent copper in the form of the complex Cu(CN)2- as the starting material for the radiolytic reduction of monovalent copper (CuCN). The experiment yields large particles of several 10 nm.
