Description
Summary:This paper describes the method of obtaining composite coatings consisting of silver nanoparticles covered by a fluoropolymer film. The morphology and optical properties of resulting coatings are given within. The presence of a surface plasmon resonance (SPR) minimum of silver nanoparticles deposited on glass and fused silica surfaces has been revealed. The paper describes a shift towards the infrared (IR) region when the average size of deposited silver nanoparticles is changed. However, coating the nanoparticles in a fluoropolymer film does not significantly shift their resonance. •Ag thin films were synthesized by vacuum gas-jet method.•Optical properties and film structure dramatically depend on synthesis condition.•Ag NPs films were covered by fluoropolymer for protection from the surroundings.•Changings of surface plasmon resonance position are discussed.
