The Third-Order Nonlinear Optical Properties and the Optical Limiting Properties of Sulfonic Metallo-Phthalocyanines
The optical limiting properties of CuPcTs, NiPcTs and CoPcTs were investigated with nanosecond pulses at the wavelength of 532nm. Among them, CuPcTs exhibits the strongest optical limiting effect. An explanation based on nonlinear absorption and refraction is provided. And also, the relationship between the d-electron configuration and the third-order nonlinear optical properties of CuPcTs, NiPcTs and CoPcTs were discussed.
