Sentence examples for by a light photon from inspiring English sources
In fluorescence, an electron is raised from a certain baseline energy known as the ground level to an excited level by a light photon or other radiation.
Basically, Raman scattering probes the inelastic scattering of a monochromatic light (photons) by the lattice vibrations (phonons) in a solid.
Such changes can be measured from the 'collecting area', which relates the number of photoactivated rhodopsin molecules produced by a light flash to the photon density of the flash (Baylor et al., 1979).
Electrons can be excited from the valence to the conduction band by light photons having an energy hν that is larger than energy gap Eg between the bands.
However, such excitation by visible light photons does not seem to be spectacularly affected.
The main structure of this kind of solar cells is built of a photoactive electrode consisting of a tin-oxide conducting glass mounted by a nanostructured wide band gap metal-oxide semiconductor thin film anchored to suitable dye molecules, which have the ability to be excited by absorbing light photons.
Unique properties related to energy storage and sub-nano scale response to external stimuli have been found that give rise to the capability for causing localized supercritical states leading to fluid boiling by visible light photons and other fundamental particles over eight orders of magnitude in the energy range (i.e., from the sub −eV to MeV range).
When zinc oxide is illuminated by the UV light (photons) and energy level of zinc oxide exceeds band gap energy to stimulate electron (e−) from the valence band to conduction band.
Dr. Raskar traces those bouncing echoes of light photon by photon, based on when and where they land.
These photons can be detected by a light sensitive device.
This contradiction can be settled by associating charges to the light photons but this must be verified experimentally and theoretically.
