Nanoribbons add color to luminescent paint

In the future, multicolored traffic signs visible at night will likely contain luminescent paint. To help realize this advance, a University of Georgia research team fabricated rare-earth activated glowing nanoribbons.

A unique synthesis process enabled the team to create the 1-D luminescent nanostructures. Capable of generating their own light, the structures produce blue, green and orange light. Individual colors result from differing lattice structures.

The synthesis method in this project could be applied to fabricate many other rare-earth, ion-activated, luminescent nanostructures for nanophotonic applications. In addition to optical paint, the nanoribbons may find application in emerging optical technologies.

Nanoribbons with different elemental compositions and lattice structures offer novel luminescence properties. This project differed from previous studies on 1-D luminescent nanostructures because it focused on lattice structures rather than on elemental and binary semiconductor materials.
