摘要:

我们报告的光电导在二维阵列的金纳米棒的纵向表面等离子体激元的频率强烈增强。该阵列是通过在SiO2衬底上的金纳米棒溶液的液滴沉积和冲压的组合形成的。我们发现等离子体激元诱导的光电导对激发光子的线偏振敏感。我们将光电导的发生解释为纳米棒的纵向表面等离子体共振激发后阵列电导的热测量增强。

英文摘要:

We report on the photoconductance in two-dimensional arrays of gold nanorods which is strongly enhanced at the frequency of the longitudinal surface plasmon of the nanorods. The arrays are formed by a combination of droplet deposition and stamping of gold nanorod solutions on SiO2 substrates. We find that the plasmon induced photoconductance is sensitive to the linear polarization of the exciting photons. We interpret the occurrence of the photoconductance as a bolometric enhancement of the arrays' conductance upon excitation of the longitudinal surface plasmon resonance of the nanorods.
