What is fluorescence?

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation. Fluorescence is commonly used in microscopy, bioassays, medical imaging, and chemical sensors.

luminescence

Luminescence is a broad term that includes fluorescence, but also encompasses other light emission processes like phosphorescence, chemiluminescence, and bioluminescence. These are alternative methods for studying similar phenomena or molecules.

Raman

Raman spectroscopy, like fluorescence, provides information about the vibrational modes of molecules. However, Raman relies on scattering of light, while fluorescence relies on the emission of light after absorption.

fluorescence Complementary Technologies

absorbance

Absorbance and fluorescence are related spectroscopic techniques. Fluorescence occurs after a molecule absorbs light, so absorbance measurements (e.g., UV-Vis) can be used to determine excitation wavelengths for fluorescence experiments and quantify the amount of light absorbed which drives the fluorescence.
