Abstract

Localized surface plasmon resonance excited in gold nanoparticles coupled with a responsive polymer gel is explored. A specially designed structure (vertically aligned cylindrical pores decorated with gold nanoparticles) of responsive polymer gel thin films allows for the transduction of external signal/ stimuli into a strong optical effect enhanced by interactions of gold nanoparticles.

摘要

研究了与响应性聚合物凝胶偶联的金纳米粒子中局域表面等离子体激元的激发。响应性聚合物凝胶薄膜的特殊设计结构（垂直排列的圆柱形孔，孔表面修饰有金纳米粒子）使外部信号/刺激能够转化为强烈的光学效应，这种光学效应通过金纳米粒子的相互作用得到增强。
