Materials Swap Improves Nanoantenna Performance, Efficiency

Light-scattering nano-elements, also known as nanoantennas due to their ability to harness light, are used as an optical control technology in nanophotonics. In combination with a phosphor plate, and upon irradiation, these 2D structures — in which nanopoarticles are arranged periodically on a substrate — achieve a mix of blue and yellow light and enable spatial and spectral control over luminescence.
