Transmission spectra of the nanostructured Au films show strong enhancement (more than 45%) in a wide range from 300 nm to 1600 nm, the measurement wavelength range. Besides a peak observed at around 500 nm in all spectra, a wider peak on the longer wavelength side was observed, which shifted to longer wavelength when periodicities of the hole arrays were increased. © 2012 Springer-Verlag. | Source Title: | Applied Physics A: Materials Science and Processing | URI: | http://scholarbank.nus.edu.sg/handle/10635/56408 | ISSN: | 09478396 | DOI: | 10.1007/s00339-012-6758-0 |
