Feature Article: Bound exciton and donor–acceptor pair recombinations in ZnO

The article [1] features the current state of knowledge on the optical properties of excitonic and donor–acceptor pair recombination in bulk n‐ZnO, as revealed by recent photo‐ and cathodoluminescence measurements. The cover picture is a photograph showing an unusual look at the green luminescence of rod‐shaped ZnO crystals under ultraviolet excitation. The first author, Bruno K. Meyer, is professor of physics at the Justus Liebig University of Giessen. His scientific interests include synthesis of semiconductor oxides by chemical vapour deposition and magnetron sputtering, in particular with respect to doping issues, materials science of electro‐ and thermochromic materials, recombination phenomena and defect characterization by magnetic resonance. This issue also contains an Editor's Choice on “Evolution of molecular ordering and phase transitions in C 60 /C 70 solid solutions” by Gabriela Rueda‐Morales and Jaime Ortiz‐López [2].
