Fluorescent sea dye. Fluorescent dyes find a wide use in industry, going under the name of "neon colors", such as: Multi-ton scale usages in textile dyeing and optical brighteners in laundry detergents; Advanced cosmetic formulations; Safety equipment and clothing; Organic light-emitting diodes (OLEDs) Fine arts and design (posters and paintings)
Common examples include fluorescent lamps, organic dyes, and even fluorspar. Longer emitters, commonly referred to as glow-in-the-dark substances, ranged from one second to many hours, and this mechanism was called persistent phosphorescence or persistent luminescence , to distinguish it from the other two mechanisms.
Fluorescein is an organic compound and dye based on the xanthene tricyclic structural motif, formally belonging to triarylmethine dyes family. It is available as a dark orange/red powder slightly soluble in water and alcohol. It is used as a fluorescent tracer in many applications. [1]
A simplified Jablonski diagram illustrating the change of energy levels.. The principle behind fluorescence is that the fluorescent moiety contains electrons which can absorb a photon and briefly enter an excited state before either dispersing the energy non-radiatively or emitting it as a photon, but with a lower energy, i.e., at a longer wavelength (wavelength and energy are inversely ...
