Carbon coated thin films of Cu or Au on fused silica glasses have been irradiated using 100 keV Ar{sup +} ions at different fluences ranging from 1x10{sup 13} to 1x10{sup 16} ion/cm{sup 2}. In this article, we explore a route to form noble metal nanoparticles in amorphous glass matrices without post irradiation annealing using low energy ion beam mixing where nuclear energy loss process is dominant. Optical and structural properties were studied using UV-Vis-NIR absorbance spectroscopy and Glancing angle X-ray Diffraction (GXRD). Results showed that Cu and Au nanoparticles are formed at higher fluence of 1x10{sup 16} ion/cm{sup 2} used in this work without annealing. The diameters of metal nanoparticles obtained from UV-Vis NIR and GXRD are in agreement.
