Tunable multiple plasmon resonance wavelengths response from multicomponent polymer-metal nanocomposite systems — •Oral Cenk Aktas, Abhijit Biswas, Ulrich Schürmann, Usman Saeed, Thomas Strunskus, Vladimir Zaporojtchenko, and Franz Faupel — Nanocomposite Research Laboratory, Lehrstuhl für Materialverbunde, Technische Fakultät der CAU, Kaiserstr. 2, D - 24143, Kiel, Germany

Nanocomposite thin films formed by noble metal nanoparticles embedded in a dielectric matrix show attractive optical properties at the surface plasmon resonance wavelength due to dielectric and quantum confinements effects. A simple method of vapor phase co-deposition has been used at elevated target temperature ( ∼ 120 ^∘C) coupled with selective masking technique to produce a multicomponent optical material with seven different UV/Vis optical active planes. Such system consists of different nanocomposites ( ∼ 100 nm) of Teflon AF/Ag, Teflon AF/Au and Teflon AF/Cu with sharp interfaces. The fabricated system has regions of single nanocomposite plane together with multilayer structures facilitating tunable double and triple particle plasmon resonance wavelength response from a single system.
