%X 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, and chemistry. Efficiency of applications of metallic NPs for laser and optical nanotechnology depends on plasmonic and thermophysical properties of NPs, characteristics of radiation, and surrounding medium. Here we present the results of comparative analysis of NP properties (plasmonic, thermooptical, and others) allowing selecting their parameters for thermoplasmonic and photonic applications. Plasmonic and thermooptical properties of several metallic (aurum, silver, platinum, cobalt, zinc, nickel, titanium, cuprum, aluminum, molybdenum, vanadium, and palladium) NPs are theoretically investigated and analysis of them is carried out. Investigation of the influence of NPs parameters (type of metal, radii, optical indexes, density, and heat capacity of NP material), characteristics of radiation (wavelength and pulse duration), and ambient parameters on plasmonic and thermophysical properties of NPs has been carried out. It was established that maximum value of thermooptical parameter (maximum NP temperature) can be achieved with the use of absorption efficiency factor of NP smaller than its maximum value. 1. Introduction Recent advances in photothermal nanotechnology based on the use of nanoparticles (NPs) and optical (laser) radiation have been demonstrated for their great potential. In recent years, the laser-NP interaction, absorption, and scattering of radiation energy by NP have become of great interest and an increasingly important for topic in photonic and laser nanotechnology [1每27] (also see the references in these papers). There are many reasons for this interest including application of NPs in different fields, such as catalysis [1, 2], laser nanobiomedicine [3每11], nanooptics and nanoelectronics [12每15], laser processing of metallic NPs in nanotechnology [16每23], and light-to-heat conversion [24每27]. Most of these technologies rely on the position and strength of the surface plasmon on a nanosphere and the fact that NP will absorb and scatter radiation energy well at resonance wavelength. Successful applications of NPs in photonics and thermoplasmonics are based on appropriate plasmonic and optical properties of NPs. High absorption of radiation by NPs can be used
