Fluorescence: meaning, definitions and examples
๐
fluorescence
[ flสษหrษsษns ]
scientific phenomenon
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It occurs when an excited electron in a molecule returns to its ground state, releasing energy in the form of light. This process is often observed in certain minerals, dyes, and biological substances. Fluorescence has applications in various fields including biology, chemistry, and even art. It is commonly used in fluorescent lamps and in fluorescence microscopy, a powerful technique in cell biology.
Synonyms
brightness, glow, luminescence
Examples of usage
- The fluorescent dye illuminated the sample under UV light.
- They use fluorescence to study cellular processes.
- The mineral glows with bright fluorescence under certain lights.

Etymology
The term fluorescence originates from the mineral fluorite, named in the 18th century, which exhibits this property. The word itself was first used in the 19th century, derived from the Latin word 'fluor', meaning 'to flow'. In the early 20th century, the phenomenon gained more scientific attention, particularly with the advent of modern physics and chemistry. Scientists began to explore the underlying mechanisms of fluorescence, leading to its use in various technologies, such as television and fluorescent lighting. As research progressed through the 20th century, fluorescence became a vital tool in biological and medical research, allowing for advancements in microscopy and diagnostic techniques. Today, it is a fundamental concept in physical chemistry and biochemistry, with ongoing research continuing to reveal new applications and insights into molecular interactions.
