✦ Synopsis


A high‐quality (0001)‐oriented ZnO layer that emits ultraviolet light at room‐temperature has been prepared by electrodeposition on a (111) Au/(100) Si substrate. The ZnO layer emits ultraviolet light at a photon energy of around 3.3 eV due to the recombination of bound excitons and visible light at 2.34–2.8 eV at room temperature. The preparation temperature for this electrodeposition technique is several hundreds of degrees less than for other known techniques.
