We propose a plasmonic crystal consisting of Si nanoparticle array placed on a metal surface with a gap between.Simulations show that this structure support lattice plasmons that have extremely narrow reflection dip,whose optical properties depend on array period,incidence angle and background refractive index.Given that lattice plasmons are highly sensitive to local environment,they can be used to enhance photoluminescence at selected wavelength,or be used as refractive index sensor.
