Luminescence Enhancement of Pyrene/Dispersant Nanoarrays Driven by the Nanoscale Spatial Effect on Mixing
This work presents a simple method to generate ordered
chromophore/dispersant
nanoarrays through a pore-filling process for a nanoporous polymer
template to enhance chromophore luminescence. Fluorescence results
combining with the morphological evolution examined by scanning probe
microscopy reveal that the enhanced luminescence intensity reaches
the maximum intensity as the nanopores of the template are completely
filled by the chromophore/dispersant mixture. The variation is attributed
to nanoscale spatial effect on the enhanced mixing efficiency of chromophore
and dispersant, that is, the alleviation of self-quenching problem,
as evidenced by the results of attenuated total reflection Fourier
transform IR spectroscopy combining with grazing incident wide-angle
X-ray diffraction. The enhanced luminescence of the chromophore/dispersant
nanoarrays driven by the nanoscale spatial effect is highly promising
for use in designing luminescent nanodevices
