On the other hand, the second NIR (1000nm-1350nm) light can penetrate into body tissue more hence it is more suitable in cancer photo-thermal therapy applications (PTT). In this paper, absorption cross sections of core-shell silica-gold are calculated using finite element (FEM) method. The results indicate that the surface plasmon frequency of these nanostructures strongly depend on the shell thickness and could easily be tuned for the second NIR.
