Preserving glow-in-the-dark art and fashion for future generations
摘要
美国印第安纳波利斯艺术博物馆的保护人员正致力于研究设计师Stephen Sprouse作品中使用的磷光与荧光颜料，以延缓其色彩褪变。Sprouse在1980年代以涂鸦印花和Day-Glo亮色闻名，其作品现藏于该馆纺织品部。相关研究进展本周在芝加哥举行的美国化学会会议上发布。磷光材料自中世纪起被记载，通过吸收并缓慢释放光能发光；1896年贝克勒尔因磷光铀盐发现
Fashionistas of a certain age no doubt remember the late designer Stephen Sprouse, who gave Blondie's Debbie Harry her distinctive Bowery punk style. Sprouse's first collections in the mid-1980s made a major splash, melding graffiti prints, a playful '60s aesthetic, and bright Day-Glo colors that won admirers such as Andy Warhol.
Several examples of Sprouse's work are preserved in the textiles collection of the Indianapolis Museum of Art at Newfields, where conservationists are trying to learn more about the phosphorescent and fluorescent pigments the designer used in his creations in order to keep the colors from dulling over time. They described recent advances in that research at a meeting of the American Chemical Society (ACS) held this week in Chicago.
Scientists began describing minerals that glowed in the dark as phosphors in the Middle Ages. Typically such materials take on a charge when exposed to light, storing the absorbed energy and releasing it gradually as re-emitted light. Henri Becquerel discovered radioactive decay in 1896 because of his work with phosphorescent uranium salts: He left the salts in a closed drawer with photographic plates, which fogged up even without a light source. DayGlo paints and similar materials exploit the related phenomenon of fluorescence. DayGlo pigments fluoresce in daylight by essentially converting UV light into visible light to produce brighter, more vibrant colors.
