Abstract
The optical limiting (OL) properties of the novel cluster cis-Cp*2Mo2S4Cu2(SCN)2 in CH2Cl2 solution are studied by using nanosecond duration laser pulsed at 532 nm wavelength. The OL effect of this cluster can be observed with a linear transmittance of 75%. The limiting threshold can be derived from the OL experimental results. In order to provide direct evidence on the physical origin of the observed OL effects, the nonlinear effects for this cluster in CH2Cl2 solution have also been investigated by time-resolved pump-probe experiments. The pump-probe experimental results of this cluster are compared with that of C60, which is measured by using the same experimental setup. And it reveals that the nanosecond OL effect may be due to the reverse saturable absorption (RSA), which is related to the excited triplet states. A theoretical model of the five-level system is presented to analyze the pump-probe results.
