Definition of luminescence in English:

luminescence

noun ˌluːmɪˈnɛs(ə)nsˌluməˈnɛsəns

mass noun

- A proportion of this energy appears in the form of light emitted by the crystal; this is optically stimulated luminescence.
- The acceleration of the recombination rate and the strong stimulation of luminescence caused by the membrane potential are well known.
- 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.
- It seems clear that the photocyte has substantial local control of its luminescence and is not dependent on external oxygen in any simple way.
- Streptococci emit light during log phase growth, and luminescence subsides as they enter stationary phase.
