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 ...

Spectroscopy, in its broadest sense, is the term given to the investigation and measurement of spectra produced when a substance interacts with or emits electromagnetic radiation. All known matter ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...

Modern instrumental chemical analysis employs a variety of techniques. Fluorescence spectroscopy is one of these methods and is based on the principle of excitation and emission of characteristic ...
