摘要
The 2D optical field intensity distribution in sub-micron, ultrathin, and crystalline gold platelets is investigated by two-photon luminescence (TPL) microscopy. In particular, the evolution of the TPL maps as the particle morphology undergoes a transition from triangular to hexagonal reveals that the signatures of the high-order surface plasmon states sustained by the platelets follows the same C-3 nu to C-6 nu symmetry redistribution. Experimental observations are precisely accounted for by heoretical simulations based on the Green dyadic method.
