摘 要：This paper showed simple and effective synthesis of copper nanoparticles within controlled diameter using direct electroless deposition on glass substrates,following the sensitization and activation steps.Electroless-deposited metals,such as Cu,Co,Ni,and Ag,and their alloys had many advantages in micro-and nanotechnologies.The structural,morphological,and optical properties of copper deposits were characterized using X-ray diffraction（XRD）,atomic force microscopy（AFM）,and UV-Vis spectroscopy.The structural data was further analyzed using the Rietveld refinement program.Structural studies reveal that the deposited copper prefers a（111）orientation.AFM studies suggest the deposited materials form compact,uniform,and nanocrystalline phases with a high tendency to self-organize.The data show that the particle size can be controlled by controlling the activator concentration.The absorption spectra of the as-deposited copper nanoparticles reveal that the plasmonic peak broadens and exhibits a blue shift with decreasing particle size.
