Preserving glow-in-the-dark art and fashion for future generations

The Indianapolis Museum of Art at Newfields safeguards a collection of Stephen Sprouse's iconic glow-in-the-dark designs, including his 1980s creations that revolutionized fashion with their bold Day-Glo colors and graffiti-inspired prints. Conservationists are diligently studying the materials used by Sprouse to prevent the dulling of his signature fluorescent pigments over time.

This research was recently shared at a conference of the American Chemical Society in Chicago, where experts unveiled recent breakthroughs in understanding the science behind these radiant materials. The discovery of phosphorescent substances dates back to the Middle Ages, and scientists initially dubbed them phosphors. However, it was Henri Becquerel's pioneering work with radioactive uranium salts in 1896 that truly unlocked the secrets of phosphorescence.

Becquerel observed that these salts, when exposed to light, could generate and store energy, which would gradually be emitted as a form of light, even in the absence of any external illumination. This phenomenon laid the foundation for the creation of fluorescent materials like DayGlo paints, which harness the power of UV light to produce more vivid and eye-catching hues.
