Abstract |
The technology of nanoscale gold films deposited onto glass by vacuum sputtering is well known in solar glazing. However, aqueous deposition of gold for this purpose appears to be rarely, if ever, commercially exploited. Nevertheless, the uniform film texture and pleasant neutral color of coatings of gold nanoparticles suggest their use in this application. The results of this research showed the optical transmission or reflection spectra obtained from such coatings, was directly related to the interplay between the rates of nucleation and growth of the particles, the manner in which they aggregated and the nature of the prior treatment of the glass surface. Samples with a similar surface coverage of gold nanoparticles may exhibit quite different transmission spectra, depending on the morphology of the coating. Different pretreatment schemes for the glass also ostensibly influenced the results because the glass surface composition and surface tension changed accordingly.
