Abstract

The localized surface plasmon resonance (SPR) spectrum of silver nanoparticles
fabricated on a thermochromatic film, vanadium dioxide (VO2), is
studied in this paper. Owing to the temperature-dependent dielectric
function Of VO2, the SPR band dramatically exhibits temperature dependence
in the range of 30-80 degrees C. The peak extinction wavelength,
ASPR, blueshifts as temperature increases and reversibly redshifts
as temperature decreases. The shift magnitude (AASPR) is strongly
dependent on the silver mass thickness, d(m); a value of 50 nm of
Delta lambda(SPR) is achieved for particles (mean diameter 51 nm)
with d(m) = 2 nm while a value of 250 nm is achieved for particles
(mean diameter 133 nm) with d(m) = 10 nm. Beyond the SPR band, it
is interesting to find that the spectral line shape of silver particles
is dominated by the imaginary part of the dielectric function Of
VO2. These results can be interpreted based on dynamical Maxwell-Garnett
theory.
