Diatoms are single‐celled algae that possess silica shells called “frustules” decorated with periodic structures ordered at the micro‐ and nanoscale. Diatom biosilica containing metabolically inserted germanium is used to fabricate an electroluminescent (EL) thin film device (see figure). The EL spectrum has a series of sharp UV line emissions at 340–380 nm and weaker bands in the blue and red range.
