Optical properties of silver nanocube surfaces
obtained by silane immobilization

Title variants
Languages of publication
Silver nanocubes were synthesized by the
polyol method and immobilized on a surface in a
simple approach using an aminopropyltriethoxysilane
(APTES). The optical and structural properties of the
polyvinylpyrrolidone (PVP) stabilized nanocubes were
investigated in solution and on glass surfaces. The SERS
enhancement factors at two excitation wavelengths
for crystal violet were compared with electric fields
arising in different nano¬particle configurations using
finite-difference time-domain simulations. They are in
agreement with the preferred face-to-face orientation
in the nanoaggregates on the surfaces. The facile
immobilization enables on-demand preparation and use
of the nanocubes in real analytical applications.
