Abstract

It is demonstrated that photoluminescence of DCJTB can be
enhanced by surface plasmons occurred in silver nanoparticle arrays on
glass substrates fabricated by using nanosphere lithography (NSL)
combined with reactive ion etching (RIE). By changing the size of the seed
polystyrene nanosphere with fixed thickness of SiO2 film as a buffer layer
between silver nanoparticles and fluorescent dye, we systematically studied
the interaction between surface plasmons in Ag nanostructures and
fluorescent dye by measuring the photoluminescence and time-resolved
photoluminescence (TRPL) of the samples. As compared with pure DCJTB,
it is observed that PL enhancement as high as 9.4 times and life time
shortening from 0.966 ns shortened to 0.63 ns can be achieved with
polystyrene nanosphere 430nm in diameter. The physical origin due to
plasmonic excitation has been clarified from 3D finite element simulations,
as well as the assistance of UV-visible reflectance spectrum.
