Elastic scattering spectra of a) Au NCA, b) TiO2 NP array and c) optoplasmonichybrid array. The spectra were recorded for arrays with periodicities of Λ = 700 nm, 800 nm, 900 nm, and 1000 nm. All spectra contain the diffractive grating orders (1, 0) (B2) and (1,1) (B1). In a) and c) the shaded areas mark the spectral position of the plasmon resonance in individual Au NP clusters (λplas ≈ 760 nm). The fitted peak wavelengths (Exp) of B1 and B2, the spectral range Equation (3) for (1,1) and (1,0) grating orders for NA = 1.2–1.4 according to Equation (3), and MSTM simulated spectral positions (MSTM) for an incident angle of θinc = 60° (φinc = 45° and 0° for (1,1) and (1,0) mode, respectively) and nr = 1.24 as function of Λ are summarized in d) for Au NCAs, in e) for TiO2 NP arrays, and in f) for optoplasmonic hybrid arrays.
