Thermal-Induced Stress of Plasmonic Magnetic Nanocomposites

Abstract

We present theoretical calculations to interpret optical and mechanical properties of Ag@Fe 3 O 4 nanoflowers. The microstructures and nature of optical peaks of nanoflowers are determined by means of the Mie theory associated with effective dielectric approximation and the experimental absorption spectrum. Under laser illumination, the thermal strain fields inside and outside the structure due to the absorbed optical energy are studied using continuum mechanics approach. Our findings provide simple but comprehensive description of the elastic behaviors of previous experiments.

Multilayered Plasmonic Nanostructures for Solar Energy Harvesting

“…Our approach could quantitatively predict future experiments. Mie theory has been used widely and successfully to calculate the absorption, scattering, and extinction spectra of multilayered nanocomposites embedded in a homogeneous and isotropic medium [1,10,19]. The approach shows a good agreement with experimental results.…”

Plasmonic Photothermal Heating of Gold Nanoshell Solutions

“…Hereafter, we fix the thickness R s − R c = 20 nm to be consistent with Ref. [3,15,19]. This finite-size effect is encoded to our dielectric function by changing the damping parameter…”

“…The absorption, scattering, and extinction cross sections of core-shell nanospheres have been theoretically calculated using Mie theory [3,[14][15][16][17][18][19]. It is well-known that theoretical calculations provide a quantitatively good agreement with experiments [15][16][17]19].…”

“…[21]. In several experimental studies [3,15,19], the shell thickness is approximately 20 nm and the finite-size effect on the optical spectrum becomes important. Hereafter, we fix the thickness R s − R c = 20 nm to be consistent with Ref.…”
