One of the mysteries of the English language finally explained.
The emission of light by a substance that has not been heated, as in fluorescence and phosphorescence.‘honey fungus produces a ghostly greenish luminescence’

- ‘The luminescence in these cases may be excited by direct electron impact rather than with UV light.’
- ‘In the nonsilenced plant, strong luminescence was detected from all parts of the section, while no luminescence was found in the control plant.’
- ‘There are different types of luminescence.’
- ‘This property also leads to the intense luminescence and electron transfer capability of porphyrins and many metalloporphyins.’
- ‘The luminescence was quantified in live cells using bioluminescence imaging.’
- ‘Pholasin alone can emit luminescence if exposed to superoxide.’
- ‘It seems clear that the photocyte has substantial local control of its luminescence and is not dependent on external oxygen in any simple way.’
- ‘Not electrical, but green luminescence; a glowing paint that had been painted along every shelf and spare inch of wall or floor.’
- ‘This might be explained by the pattern of brain generated neural bursts that initiate luminescence and this appears to be the case in P. lucicrescens.’
- ‘Chemiluminescence is a special case of luminescence in which the excitation source is a chemical reaction.’
- ‘This luminescence makes them interesting candidates for applications in biological test systems or as sensors.’
- ‘He studied seawater luminescence and ocean temperatures while charting the path of the Gulf Stream.’
- ‘Most of the arthropods consist of an infill of sparry calcite with uniform luminescence.’
- ‘Streptococci emit light during log phase growth, and luminescence subsides as they enter stationary phase.’
- ‘The acceleration of the recombination rate and the strong stimulation of luminescence caused by the membrane potential are well known.’
- ‘A proportion of this energy appears in the form of light emitted by the crystal; this is optically stimulated luminescence.’
- ‘Intriguingly, rhythmic luminescence in certain lines was affected by only a subset of the pacemaker mutations.’
- ‘When a laser light source is used to stimulate the release of electrons, the process is called optically stimulated luminescence.’
Late 19th century: from Latin lumen, lumin- ‘light’ + -escence (denoting a state).
