Abstract. In the present work, the production is reported of Cu nanoparticles, with sizes of 2–5 nm, by proton irradiation with a low controlled temperature for the sample. The process yields aggregates over a crystalline matrix of the same element. The structural evolution of the sample is analyzed from macroscopic to nanoscopic scales, using optical and electron microscopy. The grain size and preferential shape-changes of the polycrystalline sheets were obtained by optical chromatic systems. Scanning electron microscopy analysis was used to study the morphology and composition with an Energy Dispersive Spectroscopy (EDS) system, and with the help of transmission electron microscopy the lattice matrix of crystal was solved and the nanoparticles’ shape and size were determined. Molecular simulation tools were used to support the analysis of high-resolution elecron microscopic images and the nanoparticles’ behavior.
