Abstract:
Gold-silver alloy colloids were produced in epoxy resin by thermal decomposition of gold and silver complexes, and their optical absorption spectra were measured. A linear law was found for the maximal absorption wavelengths: the maximal absorption wavelength for gold-silver alloy colloids of arbitrary composition was determined from the wavelengths for pure gold and pure silver colloids and the initial concentration ratio of gold and silver complexes. The change of absorbance and absorption wavelengths with heating periods is presented. Copyright 2001 Academic Press.
