Abstract
Optical coating materials comprise a transparent matrix material having dispersed nanoparticles comprising between 1 and 20 volume percent of the optical coating material. The coating materials are used to form optical coatings on substrates, such as glass/ceramic, polymer or metal, to alter the color or other optical properties. The nanoparticles are semiconductive material or elemental metals or elemental metal alloys that exhibit surface plasmon resonance.
Claims22
An optical coating material comprising a transparent or translucent matrix material having dispersed therein nanoparticles formed of materials selected from the group consisting of semiconducting material, elemental metals, elemental metal alloys and mixtures thereof, providing that said metals and/or metal alloys exhibit a surface plasmon effect.
