Abstract:

We have simulated the extinction spectra of Au triangular nanoprisms and nanoboxes by finite difference time domain (FDTD) method. It is found that the refractive index sensitivity increases linearly and near exponentially as the aspect ratio of nanoprisms increases and wall thickness of nanoboxes decreases. A sensing figure of merit (FOM) calculations shows that there is an optimum wall thickness for each edge length and height of the box, which makes them to be promising candidate for effective sensing applications. We have also shown that the higher FOM in triangular nanoboxes compared to the cubic nanoboxes and other solid structure is inherent in the shape of nanoparticles.
