Paper Abstract

Fluorescent Colorants are widely used around the world to enhance visibility. The outstanding brightness and cleanliness of the colors lend themselves to applications in safety materials, advertising, toys, magazines, packaging, and other areas. The brightness and cleanliness is a result of the colorants ability to reradiate absorbed energy as visible light, usually shorter more energetic photons as longer less energetic photons. This can give reflectance values of well over 100%, sometimes as high as 300%, in the perceived color. A good working definition of fluorescent color is: A colorant that absorbs light energy and reradiates the energy at visible wavelengths. Light that is not absorbed is reflected, as in conventional color. Emission ceases when the excitation energy is removed.
