Submicrometer Spatial Resolution of Metal-Enhanced Fluorescence [PDF]
Applied Spectroscopy, 2003 Enhanced fluorescence emission intensity from fluorescein was observed on glass slides covered with thin films of silver nanoparticles using a confocal laser-scanning microscope. The silver nanoparticle film increased the emission intensity of fluorescein by an average of at least three-fold in the area studied. Statistics are given on the enhancement

Metal-Enhanced Fluorescence from Nanoparticulate Zinc Films [PDF]
The Journal of Physical Chemistry C, 2008 A detailed study of metal-enhanced fluorescence (MEF) from fluorophores in the blue-to-red spectral region placed in close proximity to thermally evaporated zinc nanostructured films is reported. The zinc nanostructured films were deposited onto glass microscope slides as individual particles and were 1?10 nm in height and 20?100 nm in width, as ...
