Nonlinear optical response of inorganic metal cluster MoCu3Se4(PPh3)3Cl solution

چکیده
The pump-probe response of the metal cluster MoCu3Se4(PPh3)3/CH2Cl2 solution is similar to that of CBS, which implies a nonlinear scattering origin of its nonlinearity. To testify how much the nonlinear scattering contributes to the optical limiting process, we employ a method by inserting a light collection lens in a standard OL experimental setup. Results from such an experiment show that nonlinear scattering is important when the concentration is low. For a high-concentration sample, the nonlinear energy loss is mainly related to thermal induced nonlinear absorption.

Optical nonlinearities of inorganic metal cluster m3-MoSe4Ag3„PPh3...3Cl
Optical nonlinearity and dynamic response of a novel inorganic metal cluster (m3-MoSe4)Ag3(PPh3)3Cl were studied. Large optical limiting effect was observed with the inorganic metal cluster (m3-MoSe4)Ag3(PPh3)3Cl dissolved in CH2Cl2. We also proved that nonlinear scattering contributes much to its optical limiting performance, which counts for nearly 75% of the total nonlinear energy loss used....
متن کاملNonlinear response and optical limiting in inorganic metal cluster Mo2Ag4S8(PPh3)4 solutions
We describe a series of experiments on acetonitrile solutions of an inorganic cluster molecule Mo2Ag4S8(PPh3)4 and compare them with data on a suspension of carbon particles in liquid (dilute ink). The optical-limiting behavior is measured by single-picosecond 532-nm pulses and nanosecond-long trains of these picosecond pulses. Nonlinear loss measurements are also performed with pulse trains at...

We report the optical limiting responses of a hexagonal prism cage shaped transition metal cluster MOZAg&(PPh3)4 in acetone and acetonitrile solutions to 8 4 s laser pulses. We have observed that the limiting behavior occurs in the entire visible spectrum. The limiting performance of the cluster is 1 order of magnitude better than that of a Cm-toluene solution at a wavelength of 532 nm. The non...

Presence of heavy metal ions in wastewater is an important public concern. Adsorption are commonly used technique to remove various pollutants, including the ions, from contaminated water sources. However, common methods for adsorption are not completely efficient at low ion concentrations and the adsorbent should be improved in order to reaching the acceptable levels of adsorption efficiency. ...
