Excitation wavelength
From Wikipedia, the free encyclopedia
The excitation wavelength describes the light shone on a sample to transfer energy to ("to excite") a light-reactive chemical group in any compound. Its unit is usually given in nanometers (nm).
An example is the green fluorescent protein (GFP), which can be excited with light of 488 nm, to induce a fluorescence at 509 nm.
