“…The unique optical properties of such nanostructured films are based on the fact that, in the visible region of the spectrum, resonance bands of plasmon‐polariton absorption are present and their characteristics depend on the filer and host material, on the size and shape of nanocrystallites and their concentration, and also on the morphology of the composite material . The incorporation of metal‐dielectric composites in periodic structures enables combining the SPR and the resonance phenomena that take place in it.…”

In this work we present results of theoretical and experimental investigation of the optical absorption spectra of thin films of nanocomposite materials composed of silver nanoparticles embedded in a diamond‐like carbon (DLC) matrix. The optical characteristics of DLC‐Ag nanocomposite are considered within the framework of the effective medium approximation. The evolution of plasmon resonance characteristics and optical properties due to changes of dielectric constant of DLC host and size of the embedded metal nanoparticles is studied. The experimental absorption spectra of DLC‐based silver nanocomposites deposited by reactive magnetron sputtering on fused‐silica were compared with the simulated ones. The observed redshift and broadening of the surface plasmon resonance (SPR) bands were explained using Mie scattering theory and Maxwell–Garnett effective medium theory. The obtained results suggest that a random mixture consisting of the DLC film with embedded isolated silver inclusions is a promising material for the fabrication of tunable nanocomposites in different sensing platforms.

“…This leads to the increase in the spectral width of the resonant peak, and to the decrease in its amplitude. Such a conclusion can be made through analysis [9], where it is experimentally confirmed that the resonant peak becomes lower and significantly wider compared to the theoretical calculations; however, resonant wavelengths in both cases match.…”

“…For these purposes, a number of sensing elements included in the sensors have been proposed, which are based on the occurrence of various resonance phenomena in the optical range. This is the resonance of the surface plasmon-polariton waves in the Otto-Kretschmann scheme [3][4][5][6], resonance of the surface plasmon-polariton waves in periodic structures [7,8] and waveguide resonance in dielectric grating on a metal substrate [9,10]. The operation of the sensors is based on the change in the resonant wavelength at a fixed incidence angle of the test beam or in a change in a resonant angle on a fixed wavelength when the refractive index of the analyzed medium is changing.…”

Calculations of the field distribution in the structure of the dielectric substrate/buffer layer/volume phase grating/analyzed medium were performed. It is shown that in the presence of a buffer layer with a low refractive index in the dielectric waveguide leads to a shift of the maximum field at the waveguide resonance into analyzed medium. As a result, the spectral and angular sensitivity of the corresponding sensor increases. Based on the waveguide equation, analytical expressions are obtained that connect the spectral and angular sensitivity of the sensor to the sensitivity of the propagation constant change due to the refractive index change of the analyzed medium. The conditions for the excitation of the resonance of surface plasmon–polariton waves in the structure with a metal or dielectric grating on a metal substrate are also given. The fields that occur at resonance for silver and gold gratings are calculated.

“…DLC itself can be considered as an amorphous nanocomposite consisting of the sp 2 graphite-like bonded carbon nanoclusters embedded into the sp 3 bonded carbon matrix. This material demonstrates excellent mechanical, electrical properties and, as it was demonstrated in 6,7 , it can serve as a functional optical material to produce optical sensors that are able to operate in different liquid environments. Doping of DLC with noble metal nanoparticles enables producing *tomas.tamulevicius@ktu.lt; phone +370 37 313432; fax +370 37 314423; ktu.edu/mmi nanocomposites with novel properties combining unique properties of DLC together with the plasmonic response of the nanoparticles.…”

The investigation of relaxation processes in noble metal nanoparticles upon ultrafast excitations by femtosecond laser pulses is useful to understand the origin and the enhancement mechanism of the nonlinear optical properties for metaldielectric nanocomposites. In the current work we analyze diamond like carbon (DLC) film based copper and silver nanocomposites with different metal content synthesized employing unbalanced magnetron sputtering of metal targets with argon ions in acetylene gas atmosphere. Surface morphology and nanoparticle sizes were analyzed employing scanning electron and atomic force microscopy. Optical properties of the nanocomposite films were analyzed employing UV-VIS-NIR spectrometry. Transient absorption measurements were obtained employing Yb:KGW femtosecond laser spectroscopic system (HARPIA, Light Conversion Ltd.). Energy relaxation dynamics in Cu nanoparticles showed some significant differences from Ag nanoparticles. The increase of excitation intensity hasn't show additional nonlinear effects for the excited state relaxation dynamics for both kinds of samples.
