Abstract
We studied the properties of GaP-based periodic dielectric structures with a silver layer coating which can enhance the signal of surface-enhanced inelastic light scattering (SERS). The dependences of the scattering signal intensity on the period for different structure heights were obtained. A comparison of the scattering signal intensities for SiO2 and GaP SERS-structures for laser excitation wavelengths of 532, 785 and 1064 nm was performed. The ability of GaP-based structures with a thin metal layer to enhance the signal by more than 7 orders of magnitude in the infrared frequency range was found. The dependence of the Raman signal enhancement on the thickness of the deposited layer was studied.
