活性炭及炭载铂纳米粒子光限幅特性

Optical limiting properties of active nano-carbon and nano-carbon-supported platinum particles

利用光限幅实验,研究了纯活性炭纳米粒子和炭载铂纳米粒子水溶液的非线性吸收特性,发现活性炭纳米粒子具有反饱和吸收到饱和吸收的特性,Pt纳米粒子对炭载铂纳米粒子体系具有表面等离子局域增强效应。

The nonlinear optical properties of pure active nano-carbon particles and nano-carbon- supported platinum solved in water are investigated by using the optical limiting experiments. The results show that the absorption property of nano-carbon particles changes from the saturated absorption to reverse saturated absorption when incident laser energy increases, and Pt nano-particles have the enhanced effects on the nano-carbon-supported platinum system.
