“…In recent years the absorption and scattering of radiation energy by NP have become a great interest and an increasingly important topic in photothermal nanotechnology (also see the references in these papers). There are many reasons for this interest in nanophotonics including applications of NPs in different fields, such as catalysis [1,2], nanoelectronics [3,4], nanooptics and nonlinear optics [5,6], and energetic nanotechnology (e.g., photovoltaics [7] and light-to-heat conversion [8,9]). Laser applications in nanotechnology include laser nanobiomedicine [10][11][12][13][14][15] with determination of selected properties of NPs [16,17] and laser processing of metallic NPs in nanotechnology [18][19][20][21][22][23].…”

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 of pure metallic nanoparticles in gaseous or liquid media, containing oxygen components (air, water, etc.). We numerically calculated efficiency factors of absorption K abs , scattering K sca , and extinction K ext of radiation with wavelength in the spectral interval 150-1000 nm by spherical homogeneous metallic and two-layered (metal core -oxide metal shell) nanoparticles: Al, Al-Al 2 O 3 and Zn, Zn-ZnO with core radii in the range 5-50 nm and shell thickness 5 nm. Analysis of presented results has been carried out.

The phenomenon of optical (laser) radiation heating of nanoparticles (NP) is important for applications in laser processing of NPs (laser induced transformation in NP size, shape and structure), light-to-thermal energy conversion and nanoenergy, laser nanomedicine, thermal catalysis, and so forth. It is essential to theoretically describe the temporal and spatial-temporal behavior of the NPs and the medium temperature for the analysis of experimental results and for the theoretical prediction of the unknown dependencies and new effects. Analytical and computer descriptions of heating, melting of a single NP under the action of CW and pulsed optical (laser) radiation and NP cooling after the termination of radiation action is carried out. An analytical model developed for the description of NP heating, heat dissipation and exchange with an ambience and cooling has been examined, and its accuracy and applicability has been estimated and established.

“…INTRODUCTION In recent years the absorption of radiation energy by NPs, light-to-heat conversion, heat dissipation and exchange with a surrounding material (medium), and following thermal and accompanied phenomena have become increasingly important topics in nanotechnology . Many reasons exist for this interest, including the applications of the light-to-heat conversion in nanoenergy [1][2][3][4][5][6][7][8][9][10][11][12], in photothermal laser nanomedicine [13][14][15][16] and catalysis [17,18], in laser processing of NPs (laser induced transformation of NP size, shape and structure) [19][20][21][22][23][24], etc. These advances in nanotechnology are based on the efficiency of light-to-heat conversion, thermal effects and the processes induced by the laser-NP interaction [1][2][3][4][5][6][7][8][9][10][11][12].…”

“…Theoretical investigation of the light-to-heat conversion under action of radiation on NPs [1][2][3][4][5][6][7][8][9][10][11][12] is predominantly based on the description of the processes with single NP. The light-to-heat conversion with NP ensemble practically did not investigate and only a few general equations were formulated and the estimations were made.…”

Abstract-The investigations and the use of nanoparticles (NPs), as photothermal agents in light-to-heat conversion processes in nanoenergy and nanotechnology are fast growing areas of research and applications. Analytical investigation of the light-to-heat conversion by nanoparticle ensemble under radiation action was conducted. The investigation of the influence of NPs parameters (their radii, absorption efficiency factor, density and heat capacity of NP material, concentration), the characteristics of radiation (wavelength, pulse duration, radiation beam radius), the surrounding material (its density, heat capacity, and heat conduction coefficient, characteristic length of radiation extinction) on the efficiency of the light-to-heat conversion is carried out. The possibility of thermal confinement (saving NP and material thermal energy practically without heat exchange with surrounding) has been established for single NP and irradiated volume of medium with NPs for determined time intervals. These results can be used for the description of the light-to-heat conversion processes in experimental investigations in nanoenergy and nanotechnology.
