摘要：

The pump-probe technique and transmission measurement technique were used to study the all-optical switching (A-OS) and optical limiting (OL) behavior of 2, 9, 16, 23-phenoxy-phthalocyanine (Pc1) and 2, 9, 16, 23-phenoxy-phthalocyanine-zinc (Pc2) in predominantly the monomeric solution form. The results show that the A-OS response time of Pc2 is longer than that of Pcl, and switch-off and -on times of A-OS for Pc2 are 1.2 and 11.6 Rs and for Pc1 are 2.3 and 7.8 mu s at the same intensity. Moreover, the results of OL experiments reveal that Pcl and Pc2 exhibit strong OL effect at nanosecond laser pulses. These studies make the samples a promising possibility for device realization.
