Organic phosphors glow in jewel tones

Facebook X LinkedIn Email
A new class of pure organic compounds that glow in jewel tones could lead to cheaper, more efficient and more flexible display screens, among other applications. Researchers at the University of Michigan developed a class of material that shines with phosphorescence, a property previously seen only in nonorganic compounds and organometallics. The metal-free organic crystals are white in visible light and radiate blue, green, yellow and orange when triggered by ultraviolet light. The color emitted can be manipulated by changing the chemical composition. Organic phosphors developed at...Read full article
