Full spectrum of colours in glow-in-the-dark materials
Japanese researchers have developed new materials that glow in a full range of colors with the potential to provide a real-world solution. The research team from Ryukoku University in Kyoto suggests using the materials to create clear, attractive emergency signage that doesn't depend on electricity to operate. Until now, phosphorescent colors were limited to bluish and greenish tones, which lack visibility through smoke or dust, and supposedly invoke anxiety. The new materials' rainbow of colors (including white light) should offer a more natural illumination, and may strike the fancy of the International Commission on Illumination (CIE), "the international authority on lighting" that's already suggested finding an electricity-free emergency lighting / signage system for buildings.
