The Stark effect of donor impurity states in a QD is a major subject for QD physics and applications [13,14].
Unlike conventional passive photonic band-gap, when excitons in quantum wells with Bragg frequency are affected by strong optical pump pulse at a frequency close to the frequency of exciton, it is expected that the position and width of photonic band-gap modulated through the Stark effect and the reflectivity to not be in resonance with the exciton anymore.
demonstrate that the band gap of ZnO nanoribbon can be reduced monotonically with increasing transverse field strength, demonstrating a giant Stark effect [22].
It also discusses interband absorption of light and the size quantization Stark effect in quasi-zero-dimensional nanosystems, and the advantages of semiconductor quantum dots for the study and diagnostics of biological nanosystems, as well as a new method for amino acid diagnostics using semiconductor dots, discussion of the interaction of isolated quantum dots with charged amino acids, and a theory for the interaction of an electromagnetic field with one-particle quantum-defined states of charge carriers in semiconductor quantum dots, including the effects of the resonant interaction of light with local electron states in the presence and absence of a homogeneous magnetic field.
Davies claimed the stance has had a stark effect in persuading current or would-be England internationals to stay at home.

The Stark effect is the shifting and splitting of spectral lines of atoms and molecules by an electric field.
The Stark effect results in a shift or division of the spectral lines into several components due to the presence of an electrical field.
Work and Pensions Secretary Iain Duncan Smith says the knowledge that you face an assessment has "a stark effect" on people who may be trying to defraud the system.
In the current study, the researchers used hybrid metal/semiconductor nanostructures developed through this process to experimentally demonstrate "tunable resonant coupling" between a plasmon (from metal core) and an exciton (from semiconductor shell), with a resulting enhancement of the Optical Stark Effect.
Because it does not matter which (non-resonant) colour the control laser has, the NRC team believes that laser control by the dynamic Stark effect should also be applicable to much larger molecules.
