Wavelength-dependent metal-enhanced fluorescence using synchronous spectral analysis

Metal-enhanced fluorescence from zinc substrates can lead to spectral distortion and a wavelength dependence

Broad Wavelength Range Metal-Enhanced Fluorescence Using Nickel Nanodeposits

We describe the use of surface-deposited nickel nanoparticles to enhance the fluorescence signatures of fluorophores. Different density Ni nanoparticulate substrates were fabricated and characterized using both AFM and optical absorption techniques. When fluorophores were placed in close proximity to the substrates, metal-enhanced fluorescence (MEF) was observed. The wavelength dependence of th...

Indium nanodeposits: A substrate for metal-enhanced fluorescence in the ultraviolet spectral region

We have studied a metallic substrate, composed of indium nanodeposits, for metal-enhanced fluorescence MEF in the ultraviolet UV spectral region. Indium coated slides were prepared using the thermal vapor deposition technique. Theoretical finite difference time domain simulations and experimental studies show that plasmon enhanced absorption and coupled radiation through the scattering componen...

Metal-Enhanced Fluorescence from Nanoparticulate Zinc Films.

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 characterized by Atomic Force Microscopy. The su...

Fluorescence Chemosensing of Mg2+ by Phenylhydrazone of a Difluorenylpiperidin-4-one

Magnesium is an abundant element in the environment. Magnesium ion sensing by fluorescence spectral method is of importance due to the need for the detection of the metal in the human body and the environment. In this paper, we report the Mg2+ ion sensing behavior of the phenylhydrazone derivative of a difluorenylpiperidin-4-one. The preparation method of this compound is simple. The compound s...
