Cosa (chi) è photoelectric densitometer - definizione
ENERGY MEASUREMENT OF ELECTRONS EMITTED FROM SOLIDS, GASES, OR LIQUIDS BY THE PHOTOELECTRIC EFFECT
Photoelectron spectroscopy; Photoelectron spectrum; Photoelectric spectrum
photoelectric
![The gold leaf [[electroscope]] to demonstrate the photoelectric effect. When the electroscope is negatively charged, there is an excess of electrons and the leaves are separated. If short wavelength, high-frequency light (such as ultraviolet light obtained from an [[arc lamp]], or by burning magnesium, or by using an induction coil between zinc or cadmium terminals to produce sparking) shines on the cap, the electroscope discharges, and the leaves fall limp. If, however, the frequency of the light waves is below the threshold value for the cap, the leaves will not discharge, no matter how long one shines the light at the cap.](https://commons.wikimedia.org/wiki/Special:FilePath/Gold leaf electroscope 1869.png?width=200 "The gold leaf [[electroscope]] to demonstrate the photoelectric effect.

Photoelectric flame photometer
LABORATORY DEVICE THAT CARRIES OUT A QUANTITATIVE FLAME TEST
Photoelectric Flame Photometer; Flame photometer
A photoelectric flame photometer is an instrument used in inorganic chemical analysis to determine the concentration of certain metal ions, among them sodium, potassium, lithium, and calcium. Group 1 and Group 2 metals are quite sensitive to Flame Photometry due to their low excitation energies.
Wikipedia
Photoemission spectroscopy
Photoemission spectroscopy (PES), also known as photoelectron spectroscopy, refers to energy measurement of electrons emitted from solids, gases or liquids by the photoelectric effect, in order to determine the binding energies of electrons in the substance. The term refers to various techniques, depending on whether the ionization energy is provided by X-ray, XUV or UV photons. Regardless of the incident photon beam, however, all photoelectron spectroscopy revolves around the general theme of surface analysis by measuring the ejected electrons.
