Fluorescence

Uncategorized

Strongly fluorescent pigments often have an unusual appearance which is often described colloquially as a “neon color.” It is generally thought to be related to the high brightness of the color relative to what it would be as a component of white. Fluorescence shifts energy in the incident illumination from shorter wavelengths to longer (such as blue to yellow) and thus can make the fluorescent color appear brighter (more saturated) than it could possibly be by reflection alone. One example is the phenomenon that causes certain materials shine UV exposure emitted from a lamp “black light”. From now, it is possible to include fluorescent pigments in some fibers, such as wool.
