That’s the wavelength of light usually absorbed by pure silicon dioxide, better known here on Earth as quartz. This artist’s illustration shows what WASP-17b might look like.

Printing of micro- and nanometer-scaled quartz glass structures from pure silicon dioxide opens up many new applications in optics, photonics, and semiconductor technologies. So far, processes ...

Chemically, quartz is nearly pure silicon dioxide (SiO 2). When there are no impurities, pure quartz is water-clear and often referred to as “rock crystal”.

A microscope image of a silicon-28 nanowire, with a silicon dioxide coating formed along the outside Matthew R. Jones and Muhua Sun/Rice University ...

The IMA defines quartz, for instance, as pure silicon dioxide “without regard to its environment of formation,” the authors write, noting that quartz as defined by the IMA differs from “polymorphs” of ...

The work is described in Science. The printing of quartz glass made of pure silicon dioxide in micro- and nanometer-fine structures opens up new possibilities for many applications in optics, ...

The collectors are (relatively) large "catcher's mitts"—tennis-racket-shaped collectors filled with 1,000cc of pure silicon dioxide: sand.
