Nanoparticles spectrally selective coatings

Laminates or polymer coatings containing dispersed rods or nanoshells could provide a cheap and effective solution for application of spectrally selective coatings of nanoparticles to existing structures. A novel implementation of this is to impart NIR/IR extinction properties of nanoshells to protective eyewear or contact lenses [93]. 

The applications of the nanoparticles and structures that we have surveyed here have extended from various kinds of sensors and analytical devices, through spectrally selective coatings and sinter inks to medical diagnostics and therapeutics. Nanoscale gold must surely be one of the most versatile and valuable materials systems available ... 

High enhancement of the copper localized surface plasmon absorbency was recorded at the two-layer planar system consisted of copper and silver nanoparticles prepared with successive vacuum evaporation. The result obtained may be caused by strong near-field coupling in the close-packed binary system. The effect may be used for the development of high-absorptive coatings and spectral selective nanoelements in the visible and near infrared spectral ranges.
