Abstract

We report theoretical and experimental results on two-photon absorption (TPA) cross section of thiolated small silver cluster Ag₁₅L₁₁ exhibiting extraordinary large TPA in red. Our findings provide the responsible mechanism and allow proposing new classes of nanoclusters with large TPAs which are promising for biological and medical applications.
