Umbrella-shaped diamond nanostructures make efficient photon collectors
Washington DC (SPX) Oct 22, 2015
Standard umbrellas come out when the sky turns dark, but in the nanoworld, umbrella shapes may be the next creative way to enhance light emission. Inspired by recent work to enhance the luminescence from diamond nanopillar structures, a team of researchers in Japan has discovered that "umbrella-shaped" diamond nanostructures with metal mirrors on the bottom are more efficient photon collectors than their diamond nanostructure "cousins" of other shapes. By tweaking the shape of the diamond nanostru ... read more
