Abstract
The precise control of the resonance frequency of plasmonic nanostructures is critical and depends on the size, composition, shape, and dielectric nature of the environment. The ability to control the shape and size of nanomaterials acutely depends on the fabrication technique and material design. We used a cheap and scalable method known as nanosphere lithography (NSL) to fabricate plasmonic nano-prism (NP) on glass and indium tin oxide substrate (ITO). The methods involve substrate hydrophilicity treatment, polystyrene nanosphere masking, metal deposition, and mask removal. The array and specific morphology of the fabricated NP was established using scanning electron microscope (SEM) and atomic force microscope (AFM). Finally, we used UVVis spectroscopy to determine the plasmonic resonance frequencies of fabricated NP on different substrates. The results reported herein have potential applications in surface-enhanced Raman spectroscopy (SERS), and biosensing. We also used scanning tunneling microscope to obtain high spatial resolution images of supramolecular trigrams.
