使用 5 32nm ,8ns激光脉冲研究了两种新型的基于富勒烯C6 0 结构体系的金纳米粒子合成物的光学非线性 .Z scan实验结果和理论分析的比较表明 ,材料的非线性吸收强烈地依赖于材料中的配合体 ,而非线性折射主要来自金纳米粒子的贡献 .而且与熟知的C6 0 甲苯溶液光限幅特性作了比较 ,分析了光限幅机理 .
The optical nonlinearity of two new gold nanoparticle composites based on fullerene C6 0 system has been studied by 5 32nm and 8ns laser pulses.The comparison between Z scan experimental results and theoretical analysis shows that the nonlinear absorption of the material strongly Dependent on the ligands in the material, whereas the non-linear refraction mainly comes from the contribution of the gold nanoparticles and is compared with the optical limiting properties of the well-known C6 toluene solution and the optical limiting mechanism is analyzed.
