Query: Controlling the LSPR properties of Au triangular nanoprisms and
  nanoboxes by geometrical parameter: a numerical investigation   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.
