Grouped by mechanism, photodetectors include the following devices: • Gaseous ionization detectors are used in experimental particle physics to detect photons and particles with sufficient energy to ionize gas atoms or molecules. Electrons and ions generated by ionization cause a current flow which can be measured. • Photomultiplier tubes containing a photocathode which emits electrons when illuminated, the electrons are then amplified by a chai… WebWhen light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect. This process is also often referred to as photoemission , and the electrons that are ejected from the metal are called …
