摘要: 以尿素为沉淀剂, 通过沉积-淀的方法, 制备了高分散的金纳米颗粒负载的介孔氧化锆薄膜; 以1064 nm激光为入射光束, 通过Z扫描实验测试了复合薄膜的非线性光学折射和吸收, 并计算了复合薄膜的非共振三阶非线性光学极化率(~10-10 esu), 金纳米颗粒的高分散性和氧化锆薄膜衬底的高线性折射率使复合薄膜显示了增强的三阶非线性极化率.

关键词: 金纳米颗粒, 介孔, 氧化锆薄膜, 三阶非线性光学性能

Abstract: Highly dispersed gold nanoparticles incorporated mesoporous zirconia thin films were synthesized through an easy deposition-precipitation method using urea as precipitator. The resultant composite thin films presented an enhanced off-resonant third-order optical nonlinear susceptibility of 10-10 esu measured by Z-scan technique at 1064 nm. The enhanced optical nonlinearity of the composite thin films was attributed to the high dispersion of the gold nanoparticles and the high linear refractive index of the zirconia matrix.

Key words: Au nanoparticles, mesoporous, ZrO2 thin films, third-order optical nonlinearity
