Abstract :
We numerically simulated two-photon luminescence at the near-filed interaction of a gold nanoparticle and a conductive atomic-force microscope tip (AFM) using FDTD calculation of electric field distribution. Comparison of the results of numerical simulation with the experimental data [1] gives information on the shape and orientation of the nanoparticles with a resolution surpassing that of conventional methods of atomic force microscopy.
