| Abstract: | 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. |
