Effect of Water Volume on the Growth of Silver Nanoparticles Promoted by Ultraviolet
The formation process of silver nanoparticles promoted by ultraviolet has been investigated by on-line UV-vis spectroscopy and transmission electron microscope (TEM). We firstly report that the volume of water will result in the growth of silver nanoparticles with different mechanism, UV-vis spectra show that the growth of nanopaticles presents blue-shift for reactive system with high volume water, but red-shift for that of low volume water. Moreover, experiments reveal that high water volume results in the change of the color of the silver sol accordingly.
