Photonen definition
WebPhoton upconversion (UC) is a process in which the sequential absorption of two or more photons leads to the emission of light at shorter wavelength than the excitation wavelength. It is an anti-Stokes type emission. An example is the conversion of infrared light to visible light.Upconversion can take place in both organic and inorganic materials, through a … WebMar 10, 2024 · The photon is also the "quantum," or fundamental unit, of electromagnetic radiation.
