From: Fabrication of Ordered Mullite Nanowhisker Array with Surface Enhanced Raman Scattering Effect
SERS spectra acquired from RhB adsorbed on the different substrates.
(a) The mullite nanowhisker array covered with Au particles. (b) Only the mullite nanowhisker array. (c) The pure mica substrate deposited with Au nanoparticle. All of the spectra are acquired at an excitation of 632.8 nm.
