Small blueshift

Webb26 maj 2024 · They observed a small blueshift of the band gap (∼ 80 meV) in thin ZnO layers due to quantum confinement, which is consistent with a simple effective mass theory in an infinite potential well. There is a drastic reduction in the excitonic effects near the bandgap, especially for thin ZnO on Si, which not only affects the excitonic … Webb17 juli 2012 · The PL peak near the band edge of ZnO is found to be very strong with negligible emission peaks associated with deep-level defects. Compared with that of the bare ZnO nanowire arrays, the peak position of the UV emission in ZnO/ZnTe core/shell nanowire arrays shows a small blueshift, and the intensity is reduced by a factor of 850.

Webb16 nov. 2024 · The way astronomers determine redshift (and blueshift) is to use an instrument called a spectrograph (or spectrometer) to look at the light emitted by an object. Tiny differences in the spectral lines show a shift toward the red (for redshift) or the blue (for blueshift). If the differences show a redshift, it means the object is receding away.

In general relativity one can derive several important special-case formulae for redshift in certain special spacetime geometries, as summarized in the following table. In all cases the magnitude of the shift (the value of z) is independent of the wavelength.
