As clearly appears from the Perrin–Jablonski diagram, the energy of emission is typically less than that of absorption (Stokes' shift), that is, the fluorescence emission spectrum is almost completely localized at longer wavelengths with respect to the absorption spectrum. In addition, fluorophores ...
What causes a line in an emission spectrum? A line emission spectrum is caused when energy is added to an atom. This added energy causes the electrons in the atom to jump up energy levels. When this happens, the atom is in an excited state. This state is unstable, so the electrons dro...
An optical frequency comb (OFC) is a mode-locked laser with a comb-like emission spectrum, that is, equally spaced, discrete frequency lines spread over the wide spectrum bandwidth. From: Molecular and Laser Spectroscopy, 2020 About this pageAdd to MendeleySet alert Also in subject areas: Eart...
12. Here we present a dayside thermal emission spectrum of the ultra-hot Jupiter WASP-18b obtained with the NIRISS13instrument on the JWST. The data span 0.85 to 2.85 μm in wavelength at an average resolving power of 400 and exhibit minimal systematics. The spectrum shows three water ...

On the spectrum of the reference piece, it can be noted that only switching from the high level to the low level is visible, which explains why at the start only the switching of uneven stages can be seen, followed by the switching of even stages during the following oscillation period. ...
In astronomy, the emission spectrum generally refers to the spectrum of a star,nebula, or another body. When an atom or molecule absorbs energy, electrons are bumped into a higher energy state. When the electron drops to a lower energy state, aphoton...
