Abstract: The optical absorption spetra of average size 4.2 nm CuCl clusters in near ultra violet and visible regions are determined at room temperature. The optical absorption spectra in two samples irradiated by He-Ne laser beam are also shown. A sharp peak with the width of 0.62 meV in an absorption spectrum of CuCl nanoclusters irradiated by laser beam is observed at 3.187 eV.

Key words: CuCl nanoclusters, optical absorption, laser irradiation
