This paper describes the methods to form silver clusters in solid, liquid and gas phases; the properties of clusters such as absorption bands, ESR, redox potential, EA and IP, and their catalytic behaviours in photo splitting water and photographic development processes.

The density matrix procedure was employed to calculate the frequency and intensity of main resonance scattering peak at 7 06×10 14 Hz(425nm) and a 1/2 fraction frequency resonance scattering peak at 1/2×7 06×10 14 Hz(850 nm) of silver clusters.
