Verb
Context #1 | Verb

science, chemistry

To fluoresce means to emit light when exposed to radiation, typically ultraviolet light. This phenomenon occurs when a substance absorbs energy and then re-emits it almost immediately as visible light. Fluorescence is commonly observed in various materials including minerals, dyes, and certain biological substances. The effect is used in applications such as fluorescence microscopy, fluorescent lamps, and safety markings. The duration of light emission is usually very short, often lasting only while the exciting source is present.

Synonyms

emit light, glow, light up, shine

Examples of usage

  • Certain minerals fluoresce under UV light.
  • Fluorescent markers can fluoresce in daylight.
  • Some cats' eyes fluoresce in the dark.
  • DNA samples fluoresce when treated with specific dyes.

Etymology

The term 'fluoresce' was derived from the word 'fluorescent,' which itself originated from the mineral 'fluorite' (CaF2). The name fluorite comes from the Latin word 'fluere,' meaning 'to flow,' due to its use as a flux in metal production. The phenomenon of fluorescence was first documented in the early 19th century when John Herschel observed that certain substances glowed when exposed to sunlight. The term 'fluorescence' was coined in the 1850s by the British scientist Stokes, who studied the light emitted by various materials. Over the years, the understanding of fluorescence has expanded significantly, leading to its application in many fields, such as medicine, biology, and materials science. Today, fluoresce is commonly used to describe the property of materials that emit light, particularly in scientific and industrial contexts.
