Abstract

The excited state nonlinearity and optical limiting behaviors of cubane-like shaped clusters [WSe₄(MPPh₃)₃Cl (M = Ag, Cu)] in DMF solution were studied by using a picosecond laser pulses. The excited state absorption capability of clusters [WSe₄(AgPPh₃)₃Cl] is obviously stronger than that of clusters [WSe₄(CuPPh₃)₃Cl]. Influences of skeletal atoms on excited state absorption are significant. The fluence-dependent model was used to describe the optical limiting phenomena, and the ratio of absorption cross-section of the excited state to that of the ground state of clusters [WSe₄(AgPPh₃)₃Cl] is two times greater than that of fullerene.
