This month’s Crystal Clear shows a vanadia star-shaped nanocrystal.
The crystal was made by Sarbajit Banerjee and colleagues at the State University of New York, Buffalo. They were making six-armed nanocrystallites of binary vanadium oxides, and although in this particular image the arms aren’t fully separated, we still thought it was a great looking crystal. They used a new seeded growth strategy that was very successful in making controlled shapes with good monodispersity, and you’ll have to read the full paper to see the complete nanostars!
Vanadium oxides are important in technology, partly because the variety of structures they can form makes them invaluable as host lattices, but also because of their interesting electonic, electrochromic, magnetic and optical properties. Vanadium oxides have consequently been used in batteries, as well as optical applications like laser crystals and switching devices.
