摘要：
The cross sections and efficiencies of absorption, scattering, and attenuation of laser light with λ = 532 nm and in the 475–625 nm range for two-layered spherical gold nanoparticles with radii r00 = 10, 25, 50, 75, and 100 nm and radii of the solid and liquid cores ranging from 0–r00 are calculated theoretically and studied. It is found that the variation in the optical parameters of a nanoparticle with changes in the aggregate state of the material (melting) has a decisive influence on the heating dynamics of the nanoparticle above the melting point and on the subsequent thermal processes.
