5 March 2007Third-order nonlinear optical properties and optical limiting property of metallonaphthalocyanine
Optical limiting [OL] property of naphthalocyanine zinc [ZnNc] in DMSO solution was first studied with 30 Ps laser
pulses at the wavelength of 532 nm. For comparison, OL measurement of C60 was performed under the same
experimental conditions. The results indicate that the optical limiting ability of ZnNc is similar to that of C60. To
investigate the mechanism of OL effect, Z-scan measurements were carried out with 30 ps laser pulses at the wavelength
of 532 nm, the repetition of 2 Hz. The ZnNc solution sample displays strong reverse saturable absorption effect. The OL
effect of ZnNc results from nonlinear absorption, and it can be considered as one of the most promising OL materials.
