合成表征了C60 和苯乙炔共聚物。详细地测试了聚合物溶液的光限幅性能。研究结果表明随溶液浓度增加。聚合物光限幅性能增加 ,聚合物溶液透射率为 63%时 ,在低入射激光光强时 ,透射光强度随入射光强度增加而增加 ;当入射光强度达 4.6J/cm2 透射光强开始偏离线性 ,随着入射光强进一步增加 ,透射光强逐渐达到一个饱和值 ,当入射光强为7.4J/cm2 时 ,透射光强度几乎不再随入射光强度增大而增加 ,接近一个阈值 ( 0 .94J/cm2 )。对于溶液透射率为 68%和 77%时 ,这种阈值分别约为 1 .1J/cm2 和 2 .0J/cm2 。这种聚合物呈现出明显的反饱和吸收光限幅特性。
Synthesis and characterization of C60 and phenylacetylene copolymer. The optical limiting properties of the polymer solution were tested in detail. The results show that the solution concentration increases. When the transmittance of polymer solution is 63%, the intensity of transmitted light increases with the increase of incident light intensity at low incident laser light intensity. When the incident light intensity reaches 4.6J / cm2, the transmitted light intensity begins Deviated from linearity, the transmitted light intensity gradually reaches a saturation value as the incident light intensity further increases, and when the incident light intensity is 7.4 J / cm2, the transmitted light intensity almost no longer increases with the incident light intensity increasing, approaching a threshold value 0 .94 J / cm2). The thresholds for this solution were about 1.1 J / cm2 and 2.0 J / cm2 for the solution transmissivity of 68% and 77%, respectively. This polymer shows significant reverse saturable absorption limiting properties.
