Dependences of Rayleigh and Raman scatterings from single silicon nanoblocks (W = 180 nm and 250 nm) on excitation intensity. (a, b) Experimentally measured relationships between Rayleigh scattering intensity of W = 180 nm (a) and 250 nm (b) silicon nanoblock and excitation intensity. (c, d) Calculated relationships between Rayleigh scattering intensity of W = 180 nm (c) and 250 nm (d) silicon nanoblock and excitation intensity. (e, f) Experimentally measured relationships between Raman scattering intensity of W = 180 nm (e) and 250 nm (f) silicon nanoblock and excitation intensity.
