+ - Lighting the nanoworld with nanolamps

Roland Piquepaille writes: "An interdisciplinary team of researchers at Cornell University (CU) has built 'nanolamps.' These extremely small light bulbs are made of light-emitting nanofibers about the size of a virus or the tiniest of bacteria. Using a technique called electrospinning, the researchers spun the fibers from a metallic element, the ruthenium, and a polymer. These nanofibers "are so small that they are less than the wavelength of the light they emit." Apparently, these nanofibers are easy to produce. But before they can be integrated into our increasingly smaller electronic devices, there still is a need to know how long these nanolamps can last. Read more for additional references and a picture of the orange glowing organic nanodevices."
