Extreme Light Concentration Inside Plasmonic Gold and Silver Nanoparticles During Laser Irradiation
(Springer, 2015)Computer modeling of the distributions of laser radiation intensities concentrated inside spherical gold and silver nanoparticles with the radii in the range 10–100 nm was carried out during laser irradiation with wavelengths 400, 532, and 800 nm. Distributions of laser intensity are inhomogeneous for investigated values of nanoparticle sizes and laser wavelengths. Here, we show ...2018-09-11 -
Influence of Shell Parameters on Optical Properties of Spherical Metallic Core-Oxide Shell Nanoparticles
(2015)Different metal homogeneous nanoparticles have been extensively studied in recent years due to their wide range of potential applications. It is very interesting to investigate core-shell nanoparticles with oxide shell from core metal. The formation of oxide shell on metallic nanoparticles can be achieved by different chemical and physical methods including also natural oxidation ...2017-11-04 -
Light-absorption selection of nanoparticles and nanofluids containing nanoparticles for their effective heating by solar radiation
(Springer, 2017)Light-absorption selection of single nanoparticle for solar radiation requires the simultaneous fulfillment of all of the following novel conditions—maximal close (overlap) of the dependence of nanoparticle efficiency absorption factor on wavelength with the dependence solar irradiance, predominant role of nanoparticle absorption over its scattering, the use of maximal values of ...2023-05-10 -
Nonlinear thermo-optical properties of two-layered spherical system of gold nanoparticle core and water vapor shell during initial stage of shell expansion
(2011)Nonlinear thermo-optical properties of two-layered spherical system of gold nanoparticle core and water vapor shell, created under laser heating of nanoparticle in water, were theoretically investigated. Vapor shell expansion leads to decreasing up to one to two orders of magnitude in comparison with initial values of scattering and extinction of the radiation with wavelengths ...2018-03-06 -
Plasmonic and Thermooptical Properties of Spherical Metallic Nanoparticles for Their Thermoplasmonic and Photonic Applications
(Hindawi Publishing Corporation, 2014)Investigations and use of nanoparticles (NPs) as photothermal (PT) agents in laser and optical nanotechnology are fast growing areas of research and applications. The potential benefits of NPs applications include possibility for thermal imaging and treatment of materials containing of NPs, applications of NPs for light-to-thermal energy conversion, in catalysis, laser nanomedicine, ...2016-05-11
