Abstract:
The maximum resonance scattering peak of the silver colloids prepared by ultraviolet-photochemical method is at 470 nm and the maximum absorption peak is at 412.2 nm. The intensity of resonance scattering light is linear to the silver concentration in the range of 0.456-9.12 micrograms.mL-1. It is the first time that the blue silver colloid was prepared photochemically. Its maximum resonance scattering peak is at 470 nm. It has two absorption peaks at 397.4 and 623.4 nm.
