Metal-Enhanced Fluorescence (MEF): Physical Characterization of Siver-Island Films and Exploring Sample Geometries.
In this study we have analyzed metal-enhanced fluorescence (MEF) effects from different density silver island films (SiFs) and the effects of sample geometry on the observed enhancement of fluorescence (EF). It is shown that silver islands grow exponentially with SiF deposition time (DT<7min), optical density of SiFs almost linearly depends on DT; electrical conductivity is zero. At DT>7 min, s...
متن کاملAn Evanescent Wave Fiber Optic Biosensor Based on Metal-Enhanced Fluorescence (MEF)
Fiber-optic biosensors play a significant role in the development of biosensors because they can provide miniaturized and lowcost systems. Recently, there have been explosive developments in the Metal-Enhanced Fluorescence (MEF) technology to favorably modify the spectral properties and to alleviate photo-physical constraints. We report the development of core/shell nanoparticles with the silve...
متن کاملMetal-enhanced fluorescence.
Fluorescence spectroscopy is entrenched throughout the life sciences today and is used for a variety of applications, including the detection of chemical or biological analytes/species, in reporting molecular events or for the understanding of microenvironments, such as local viscosity, polarity and voltage measurements, to name but just a few. In the majority of these fluorescencebased measure...
متن کاملMetal-enhanced e-type fluorescence.
In this letter, we report metal-enhanced e-type fluorescence. Eosin in close proximity to silver island films (SiFs) shows enhanced e-type fluorescence with an approximately two-fold higher intensity observed from SiFs, as compared to a control sample. Our findings suggest two complementary mechanisms for the enhancement: surface plasmons can radiate e-type delayed fluorescence efficiently and ...
متن کاملMetal-enhanced fluorescence exciplex emission.
In this letter, we report the first observation of metal-enhanced exciplex fluorescence, observed from anthracene in the presence of diethylaniline. Anthracene in the presence of diethylaniline in close proximity to Silver Island Films (SIFs) shows enhanced monomer and exciplex emission as compared to a non-silvered control sample containing no silver nanoparticles. Our findings suggest two com...
