Fluorescence intermittency is one exception. At the dawn of modern quantum mechanics, Niels Bohr predicted ‘quantum jumps’ of electrons between discrete energy levels of atoms and molecules.

Spectrofluorometers measure the fluorescence of molecules after being exposed to and absorb light. When molecules absorb light, the electrons become excited from their ground state into an excited ...

The fluorescence correction, F, accounts for the secondary fluorescence of target atoms by primary X-rays (i.e. X-rays produced from collisions of electrons from our source with target atoms) or ...

The speed difference between fluorescence and phosphorescence is driven by what happens after electrons from the electrical current running through the OLED material slide into the high energy level ...

and the resulting X-ray fluorescence is detected. This mode is suitable for dilute or inhomogeneous samples, such as nanomaterials or biological systems, and provides surface-sensitive information. In ...
