Press release: When hydrogen glows red

A team of German and Dutch scientists synthesized a series of substances, which show bright luminescence under UV light.

 “The compounds decompose upon contact with oxygen or moisture. Because of that, all chemicals must be thoroughly dried in specialized vacuum ovens and all manipulations must be carried under an argon atmosphere”, says Dr. Nathalie Kunkel, visiting scientist at the Chair of Inorganic Chemistry with Focus on Novel Materials of Prof. Dr. Thomas Fässler at the Technical University Munich.
