scintillation

[ sin-tl-ey-shuhn ]

noun

1. the act of scintillating; sparkling.
2. a spark or flash.
3. Astronomy. the twinkling or tremulous effect of the light of the stars.
4. Meteorology. any small-scale twinkling or shimmering of objects that are viewed through the atmosphere, caused by an interception of the observer's line of view by inhomogeneities in the atmospheric refractive index.
5. Physics.
   1. a flash of light from the ionization of a phosphor struck by an energetic photon or particle.
   2. random fluctuation of the amplitude, phase, or polarization of an electromagnetic wave.
6. (on a radar display) a slight, rapid shifting of a spot of light or the image of an object about its mean position.

/ ˌsɪntɪˈleɪʃən /

noun

1. the act of scintillating
2. a spark or flash
3. the twinkling of stars or radio sources, caused by rapid changes in the density of the earth's atmosphere, the interplanetary medium, or the interstellar medium, producing uneven refraction of starlight

Word History and Origins

Origin of scintillation¹

First recorded in 1615–25, scintillation is from the Latin word scintillātiōn- (stem of scintillātiō ). See scintillate, -ion

Example Sentences

With each technological shift, the scintillation of new possibilities meets the tug of obsolescence.

From New York Times

Additionally, organic plastic scintillators suffer from low scintillation yields and low particle radiation tolerances due to their low electron density, which hampers their single-proton detection sensitivity.

From Science Daily

The research team has put forward and substantiated a novel theory regarding the scintillation mechanisms induced by protons in CsPbBr3 nanocrystals.

From Science Daily

They have verified that proton-induced scintillation primarily arises from the population of the biexcitonic state in CsPbBr3 nanocrystals, facilitated by the process of proton-induced upconversion and impact ionisation.

From Science Daily

This finding represents a significant contribution to the understanding of proton scintillation in perovskite nanocrystals.
