Fluorescent - What does fluorescent mean?
Definition of FLUORESCENT:
A property of materials defined as the ability to emit light after absorbing electromagnetic radiation such as visible or UV light. The emitted light usually has a longer wavelength than the absorbed radiation; this is clearly seen is one of the most common examples of fluorescence, when UV light (that is invisible to the human eye) is absorbed and then emitted as visible light. It has a number of practical applications including mineralogy, gemology, geology, chemical analysis, medical tests and research, forensics, security stamps or markers, fluorescent lighting, and LED lamps. As these materials reflect visible light and emit long wavelength light together, they can also be used as extremely vivid and strong colourants to be displayed either in natural light or under UV lighting or black lighting (which will cause these materials to fluoresce and be perceived by the human eye as having a “glow”). This makes these materials ideal for uses such as high visibility clothing, decorative paints, and warning signs.
In labelling, fluorescent materials can be used to make coatings and face materials or as a component of fluorescent inks; they are chosen primarily for their high visibility and/or their decorative finish, but can also be used to print security labels.Go Back to Glossary
