摘要

Optical nonlinearities of gold nanoparticles protected by ligands have been investigated by Z-scan technique. Absorptive and refractive optical limiting (OL) effects have been measured with 8 ns duration laser pulses at 532 nm. Significant differences have been found experimentally for these two nanoparticles that differ only by their ligands. Such differences indicate that nonlinear optical responses in two nanocomposites are strongly influenced by the surface plasmon resonance of gold nanoparticles and also the nature of ligands. Both of these two nanocomposites show stronger refractive optical limiting effects than C60 in toluene.

摘要

A new approach to superior optical limiting materials, utilizing planar 'open' skeleton heterothiometallic clusters, is reported by incorporating heavy atoms and altering cluster skeletons and is found to decrease the limiting thresholds to as low as 0.07 J cm-2, among the best for OL materials.

【期刊论文】Signs alteration of nonlinear refraction of cubane-like shaped clusters from nanosecond to picosecond pulses

摘要

The excited -state nonlinear refraction of a novel cubane-like shaped metal cluster MoOS3ICu3 (2-Mepy)3 IN DMF solution is studied by using Z-scan measurement technique with laser pulses of 10 ns and 40 ps pulse width at the wavelength of 532 nm, respectively. For picosecond pulses the compound possesses a self-focusing property, the positive nonlinear refraction is attributed to population transitions among singlet states, while for nanosecond pulses it exhibits a self-defocusing property and the negative nonlinear refraction is attributed to population relaxing to triplet states.
