To enhance the two-photon excitation we deposited bis (n-butylimido) perylene films on top of gold nano-islands. The observed transient response in the reflectivity spectrum of bis (n-butylimido) perylene is due to a depletion of the molecule�s ground state and excited state absorption.}, url = {/files/mazur/files/rep_640.pdf}, author = {C.
