    FIGURE 1. Artistic rendering showing the directional ultrabright upconversion light. Two distinct photon modes, one bright and one dark, are symbolized as luminous rays engaged in a dynamic exchange of energy within a conceptual shell, on top of the nanostructure hosting the nanoparticles where this phenomenon unfolds.
    Researchers from Italy, Singapore, and the U.S. discover a new way to trap light at the nanoscale—and it has an extremely broad range of potential applications.
