What is fluorescence? Fluorescence is a light signal detected when a chemical compound called a fluorophore absorbs energy at a specific wavelength, causing it to become excited.

The meaning of FLUORESCENCE is luminescence that is caused by the absorption of radiation at one wavelength followed by nearly immediate reradiation usually at a different wavelength …
