Heat Dissipation of Resonant Absorption in Metal Nanoparticle-Polymer Films Described at Particle Separation Near Resonant Wavelength

Figure 2

Measured extinction versus simulated absorption and heat dissipation. (a) Steady-state thermal profiles from FEA simulation (bottom), measurement (top) projected of the 1.17 × 10¹² NPs/cm³ AuNP-PDMS film. (b) Power dissipated thermally (-axis) versus optically extinguished power (-axis) taken from measured extinction and CDA estimates. Top-axis identifies NP concentration for each of six datasets. Inset shows linear increase in extinguished power with increased incident power for the 3.52 × 10¹² NPs/cm³ AuNP-PDMS film. Error bars in (b) result from upper- and lower-limit ambient temperature calculations.
