A research team has studied the fluorescence of carbon nanotubes (CNTs) made from graphene sheets a single atom thick. Various hexagonal organic molecules were bonded to the CNTs' outer wall. The ...

This method uses fluorescence to analyze the samples. In fluorescence, the fluorophore absorbs light of a certain wavelength, which then excites the electron, which moves from ground state to a high ...

Researchers at the National Institute of Standards and Technology (NIST) have developed two new calibration tools to help correct and validate the performance of analytic instruments that identify ...

An interview with Michelle Gal, PEng, which explores the factors researchers must consider when choosing a suitable fluorescence illumination system for specific life sciences applications, conducted ...

Spatially-resolved steady state widefield microscopic PL image response to a carrier density gradient. The fluorescent images were simultaneously recorded at two separate wavelength regions. The image ...

Fluorescence spectroscopy is a powerful tool that is used to identify the presence of both inorganic and organic molecules in complex systems. This can be achieved in one of two ways: either utilizing ...

Fluorescence filters are at the heart of every Fluorescence optical device, and high quality filter sets are essential for high definition imaging and fluorescence microscopy. At Shanghai Optics we ...
