英英字典
- the emission of light or other radiation from atoms or molecules that are bombarded by particles, such as electrons, or by radiation from a separate source. The bombarding radiation produces excited atoms, molecules, or ions and these emit photons as they fall back to the ground state
- such an emission of photons that ceases as soon as the bombarding radiation is discontinued
- such an emission of photons for which the average lifetime of the excited atoms and molecules is less than about 108 seconds
