Using YAG laser, the nonlinear optical refractive indexes of three kinds of metal phthalocyanines in DMF, ZnPCS(C6H32N8S4Zn), AlPCS (C56H32AlClN8S4) and AlPCP (C6H32AlClN8O4) were studied with the method of Z-scan. Their third-order susceptibilities chi(3) were also calculated. The result shows that different central ion and different substituents could affect their third-order susceptibilities. The mechanisms of third order optical nonlinearity and energy transfer in the photodynamic therapy were discussed.
采用YAG激光，运用Z扫描方法研究了三种金属酞菁化合物ZnPCS（C6H32N8S4Zn）、AlPCS（C56H32AlClN8S4）和AlPCP（C6H32AlClN8O4）在N，N-二甲基甲酰胺（DMF）中的非线性光学折射率，并计算了它们的三阶极化率χ(3)。结果表明，中心离子和取代基的不同会影响其三阶极化率。探讨了三阶光学非线性及光动力治疗中的能量转移机制。
