Fluorescence (Noun)
Meaning
Light emitted during absorption of radiation of some other (invisible) wavelength.
Classification
Nouns denoting natural phenomena.
Examples
- The glow of the fluorescence was visible under the black light as the molecules excited by the ultraviolet radiation released excess energy.
- In medical imaging, fluorescence is used to visualize structures or events within living organisms, often achieved through targeted protein labeling.
- Emitting light at a longer wavelength than the absorbed radiation is a characteristic of fluorescence, distinguishing it from other types of emission.
- During the fluorescence process, energy is absorbed by a molecule, which then transitions to a higher energy state before relaxing and emitting the stored energy as a longer wavelength of light.
- Fluorescence microscopy relies on the principle that certain molecules can absorb light at one wavelength and then emit light at another wavelength to form high-contrast images.
