  A pure nanodiamond, though, doesn't reveal much about its environment. But it wasn't quite that simple. The high density of this particle shower and the use of a reactor to irradiate a much larger quantity of material mean that it is easier and far more affordable to produce dozens of grams of rare nanomaterial at once, which is approximately one thousand times more than scientists have thus far been able to obtain through comparable irradiation in accelerators.
Paper Context: Oxidation further improved the solubility of both irradiated and non-irradiated samples and led to stabilization of luminescence. We observed bleaching of the non-oxidized samples, while oxidized nanoparticles did not bleach over tens of minutes of measurements. Overall, our data point towards effective creation of photoluminescent point defects in cubic SiC nanoparticles and demonstrate the capability of our irradiation method for nanomaterials other than NDs.
