Plasmonic response of metallic nanoparticles embedded in glass and a-Si
The optical properties of nanoparticle (NP) metals displaying the highest plasmonic response (silver, gold, copper and aluminium) are simulated. Embedding the metal NPs in a dielectric medium provides prevention from agglomeration, increased absorption and protection from environmental effects. Hence, embedding is an effective method to improve the performance of plasmonic-based devices. The NPs of the aforementioned metals were simulated in air, glass and a-Si environment from the ultraviolet to the near-infrared range. Spheres, nanobars and nanoprisms of volume equal to spheres of diameter 50–200 nm were studied in a broad wavelength range of 200–1800 nm. The effect of the material, size, shape and environment was observed quantitatively by analysing the peak shifts of the dipole and higherorder poles. The highest extent of peak shift due to change in size and surrounding environment was for aluminium, followed by silver, gold and copper.
