Paradoxes in laser heating of plasmonic nanoparticles

Luk-yanchuk, Boris S; Miroshnichenko, Andrey; Tribelsky, Michael I; Kivshar, Yuri; Khokhlov, Alexei R

Description

We study the problem of the laser heating of plasmonic nanoparticles and demonstrate that, in sharp contrast to the common belief, a particle with a small dissipative constant absorbs much more energy than the particle with a large value of this constant. Even higher effective absorption may be achieved for core-shell nanoparticles. Our analysis uses the exact Mie solutions, and optimization of the input energy is performed at a fixed fluence with respect to the particle size, wavelength and...[Show more]
