Antireflection properties of composite zeolite gold nanoparticles film

The influence of gold nanoparticles on the antireflection properties of a thin film of zeolite 3A has been investigated. A low-temperature technique combining zeolite deposition with pulsed-laser gold deposition was used for the fabrication of a composite thin film on a silicon substrate. Experimental results obtained by modulation-polarisation spectroscopy showed that the antireflection effects in polarised electromagnetic radiation can achieve a decreased degree of reflectivity in a wide spectral range due to the presence of plasmonic nanoparticles on the surface of the film.
