Nonlinear optical response of inorganic metal clusters (u3-MoSe4) X3(PPh3)3Cl (X=Cu Ag)

摘要

Optical limiting effects in cubane-like metal clusters dissolved in dichlormethane have been studied by measurements of nonlinear transmissions, nonlinear scattering, and pump-probe. The nonlinear transmission measurements show that there are strong optical limiting effects in these two cluster solutions; and the silver- containing cluster has larger limiting properties than the other. The nonlinear scattering results indicate that nonlinear scattering is responsible for the limiting action in both clusters. And the pump-probe experiments show that the nonlinear scattering is thermal in origin.
