Silver nanoclusters were prepared by flow-levitation technique. The nucleation and growth mechanism of the nanoclusters were studied theoretically, and the experiment conditions and technological parameters were studied experimentally. The morphology, granularity, structure, chemical components and electronic structure properties of the as-grown silver nanoclusters were characterized. The results indicate that the average size and dimension distribution of the nanoparticles mainly depend on the cooling efficiency, flow rate and inert gas pressure of the inert gas, and the temperature and size of the metal drop. Only He was used as the carrying gas for producing particles with an average size less than 10 nm. The optical absorption spectra of Ag nanoclusters show that the value of the surfa
