Abstract:
Solar glazing based on reflective or absorptive coatings of noble metals or dielectric
compounds respectively is well-known. However, the use of gold nano-particles in an
absorptive role has hardly been considered. The performance of such coatings was assessed
using an array of incandescent lamps as radiation source, and the results ranked
against commercial glazing systems. The nanoparticle coatings attenuated the radiation
by 40%. An additional 15% of the incoming energy was convected off the inside surface
of the glass. The neutral color and simple manufacture of the coatings suggests that they
might have applications on architectural glass.
