Conservationists at the Indianapolis Museum of Art at Newfields are studying the chemical composition of phosphorescent and fluorescent pigments in the work of late fashion designer Stephen Sprouse to prevent the materials from fading over time.
Preserving Stephen Sprouse Fashion Archives
Several examples of Sprouse’s work are currently preserved in the textiles collection at the Indianapolis Museum of Art at Newfields. The designer gained international recognition in the mid-1980s for pioneering a distinct Bowery punk aesthetic for musicians like Debbie Harry, combining graffiti prints, bright Day-Glo colors, and a playful 1960s sensibility that attracted collaborators such as Andy Warhol. Over decades, however, the specialized pigments used to create those signature neon hues present significant degradation challenges for museum conservationists.
The Chemistry of Glow-in-the-Dark Materials
To understand how these textiles degrade, researchers study the fundamental chemistry behind luminescence, which dates back centuries in scientific literature. According to historical scientific definitions, materials that glow in the dark were categorized as phosphors as early as the Middle Ages. These substances typically capture a charge when exposed to light, store that absorbed energy internally, and release it slowly as re-emitted light over a prolonged period. This phenomenon played a direct role in major scientific breakthroughs of the 19th century. As documented in scientific history, Henri Becquerel discovered radioactive decay in 1896 while investigating phosphorescent uranium salts, noticing that the salts fogged photographic plates stored nearby in a closed drawer even without an external light source.
Fluorescence and DayGlo Pigments in Design
Modern synthetic creations like DayGlo paints utilize a closely related optical property known as fluorescence rather than traditional long-lasting phosphorescence. DayGlo pigments function in daylight by converting ultraviolet light into visible light spectrums, a process that yields noticeably brighter and more vibrant colors than standard chemical dyes. Conservation teams at Newfields are examining how these fluorescent mechanisms behave under museum display conditions to ensure the neon garments retain their visual impact for future generations.
