Fluorescence occurs as a result of sclerotization and increases in intensity with each successive instar.

Fluorescence is most effective when there is a larger ratio of atoms at lower energy levels in a Boltzmann distribution.

Other optical techniques are also used: Fluorescence Correlation and Cross-Correlation Spectroscopy ( FCS / FCCS ) can be used to gain information of fluorophore mobility in the membrane, Fluorescence Resonance Energy Transfer ( FRET ) can detect when fluorophores are in close proximity and optical tweezer techniques can give information on membrane viscosity.

Fluorescence is at a maximum when there is no oxygen present.

Fluorescence is when a molecule emits light of one wavelength after absorbing light of a different wavelength.

Fluorescence and Auger electron yields as a function of atomic number for K shell vacancies.

Fluorescence of a molecule is quenched by specific analytes, e. g., ruthenium complexes are quenched by oxygen.

Fluorescence of certain rocks and other substances had been observed for hundreds of years before its nature was understood.

Fluorescence is generally measured at a 90 ° angle from the excitation source to minimize collection of scattered light from the excitation source, often such a rotation is provided by a Pellin-Broca prism on a turntable which will also separate the light into its spectrum for closer analysis.

* Immunostaining of cells on slides by Microscopy ( ImmunoHistoChemistry or Fluorescence ), on microplates by photometry including the ELISPOT ( and its variant FluoroSpot ) to enumerate B-Cells or antigen-specific cells, in solution by Flow cytometry

Fluorescence and Raman measurements reveal that the Nd < sup > 3 +</ sup > doped YAG nanomaterial is comparable in quality to its single-crystal counterpart in both its radiative and non-radiative properties.

This includes the Optical Microscope, Transmission Electron Microscope, Scanning Electron Microscope, Fluorescence Microscope, and by Confocal Microscopy.

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation.

Fluorescence quantum yields are measured by comparison to a standard.

Fluorescence in minerals is caused by a wide range of activators.

Fluorescence in several wavelengths can be detected by an array detector, to detect compounds from HPLC flow.

Fluorescence in the life sciences is used generally as a non-destructive way of tracking or analysis of biological molecules by means of the fluorescent emission at a specific frequency where there is no background from the excitation light, as relatively few cellular components are naturally fluorescent ( called intrinsic or autofluorescence ).

* FLIM ( Fluorescence Lifetime Imaging Microscopy ) can be used to detect certain bio-molecular interactions that manifest themselves by influencing fluorescence lifetimes.

In the past the assay was conducted by using the touchstone method but currently ( most often ) it is done using X-ray Fluorescence ( XRF ).

Fluorescence is schematically illustrated with the classical Jablonski diagram, first proposed by Jablonski in 1933 to describe absorption and emission of light.

Like classical T Tauri stars, many brown dwarfs are surrounded by disks of gas and dust which accrete onto the brown dwarf .< ref name = uv > First Ultraviolet Spectrum of a Brown Dwarf: Evidence for H < sub > 2 </ sub > Fluorescence and Accretion, John E. Gizis, Harry L. Shipman, and James A. Harvin, Astrophysical Journal 630, # 1 ( September 2005 ), pp. L89 – L91.

Fluorescence microscopy with fluorescent reporter proteins has enabled analysis of live cells by fluorescence microscopy, however cells are susceptible to phototoxicity, particularly with short wavelength light.

Fluorescence microscopy is central to many techniques which aim to reach past this limit by specialised optical configurations.

Fluorescence lifetimes can be determined in the time domain by using a pulsed source.

Fluorescence Resonance Energy Transfer, also known as Foerster Resonance Energy Transfer ( FRET in both cases ) is the term given to the process where two excited " fluorophores " pass energy one to the other non-radiatively ( i. e., without exchanging a photon ).

Usually the setup of a Fluorescence assay involves a Light source, which may emit an array different wavelengths of light.

Fluorescence microscopy takes a fundamentally different approach to generating a light microscope image compared to transmitted or reflected white light techniques such as phase contrast and differential interference contrast microscopy.

Fluorescence microscopy requires intense, near-monochromatic, illumination which some widespread light sources, like halogen lamps cannot provide.

Fluorescence recovery after photobleaching ( FRAP ) denotes an optical technique capable of quantifying the two dimensional lateral diffusion of a molecularly thin film containing fluorescently labeled probes, or to examine single cells.

Fluorescence particles are not considered as fluorophores ( quantum dot: 2-10 nm diameter, 100-100, 000 atoms )

Fluorescence spectroscopy aka fluorometry or spectrofluorometry, is a type of electromagnetic spectroscopy which analyzes fluorescence from a sample.
