Analysis of optical properties of spherical metallic nanoparticles for effective absorption of solar radiation and their heating

摘要

The investigations and the use of nanoparticles as photothermal agents in solar and photonic nanotechnology represent a fast growing area of research and applications. Potential benefits include the possibility for the applications of nanoparticles for absorption of solar radiation, a light-to-heat conversion, for applications in nanoenergy, solar cells, photocatalysis, etc. The efficiency of applications of metallic nanoparticles for solar and photo-thermal nanotechnology depends on thermo-optical properties of nanoparticles, characteristics of radiation and surrounding medium, etc. Here we present the results of comparative analysis of the optical properties of metallic nanoparticles allowing to select their parameters for effective nanosolar and nanophotonic applications.
