Structuring of nanorods for sensing applications — •Rico Eißmann, Andreas Hille, and Lukas M. Eng — Institut für Angewandte Photophysik, Technische Universität Dresden, D-01062 Dresden, Germany

Metal nanorod arrays are elegant for various sensing applications. The fabrication of nanorod arrays is an established technique. [1] In this study graded nanorod arrays, having a variably tuned rod diameter, are investigated. In combination with integrating such graded nanorod arrays on CCD/CMOS chips it allows for very small sensor applications.

The optical and plasmonic properties of those graded nanorod arrays are calculated with the multiple multipole method [2]. The distinct plasmonic behavior of nanorods with different geometric parameters (volume, rod length and distance) allows to use them as an optical filter on light-sensitive electronic devices, and moreover to record spectrally selected wavelengths.
