Leuchtfarben

Leuchtfarben, also known as fluorescent colors, are pigments or dyes that absorb light energy in the ultraviolet or visible spectrum and then re-emit it as visible light. This re-emission occurs at a longer wavelength than the absorbed light, resulting in a perceived brightness and intensity that is significantly higher than that of conventional, non-fluorescent colors. This phenomenon is due to the presence of specific chemical compounds called fluorophores.

The effect of leuchtfarben is most pronounced under ultraviolet light, which is often invisible to the human eye. However, many leuchtfarben also exhibit their enhanced brightness in daylight due to the presence of UV components within natural sunlight. The colors appear to "glow" because the emitted light adds to the light reflected by the object, making it seem brighter than surrounding objects that only reflect ambient light.

Leuchtfarben find widespread application in various fields. In safety signage and high-visibility clothing, they are crucial for increasing conspicuity, especially in low-light conditions or busy environments. They are also used in advertising, art, textiles, and even in scientific research for tagging and tracing purposes. The intensity and specific hue of a leuchtfarbe depend on the chemical structure of the fluorophore used.
