| Abstract [eng] |
Localized surface plasmon resonance (LSPR) in isolated noble metal nanoparticles (NPs) such as Ag or Au is notorious for confining electromagnetic fields at subwavelength scale. This effect can be utilized in range of applications including but not limited to bioimaging, surface – enhanced Raman scattering, and catalysis [1]. One field of particular interest is energy harvesting where resonant absorption band can be tuned in accordance with the structural absorption of the device seeking for efficiency [2]. Moreover, there have been reports on nearly perfect plasmonic absorbers with different host matrixes covering ultra-wide wavelength range [3]. Use of diamond-like carbon (DLC) as a matrix would be advantageous in such structures due to its chemical, mechanical stability, and deposition tailored optical properties [4]. An expression for calculation of effective dielectric function 𝜀𝜀𝑒𝑒𝑒𝑒𝑒𝑒 which accounts for nanoparticle size dispersion with radius 𝑅𝑅 distribution 𝑃𝑃(𝑅𝑅) in nanocomposite follows from Modified Maxwell- Garnett Mie (MMGM) theory [5]: [...]. |
