Properties of the oxygen vacancy in ZnO
Detlev M. Hofmann,D. Pfisterer,Joachim Sann,Bruno K. Meyer,Ramón Tena-Zaera,Vicente Muñoz-Sanjosé,Thomas Frank,Gerhard Pensl +7 more
TL;DR: In this paper, deep level transient spectroscopy (DLTS) results suggest a correlation between the broad unstructured emission at 2.45 eV (green band) and a donor level 530 eV below the conduction band, it is attributed to the VO 0/++ transition.

N. Volbers,Huijuan Zhou,Christoph Knies,D. Pfisterer,Joachim Sann,Detlev M. Hofmann,Bruno K. Meyer +6 more
TL;DR: In this paper, the authors investigated cobalt doped ZnO nanoparticles prepared by using wet chemical methods and characterized the electronic structure as well as the optical and magnetic properties of Co2+ nanoparticles.

TL;DR: In this article, the generation of defect center E4 subsequent to annealing in different ambients was monitored by conducting electron irradiations with energies, where either both the Zn- and O-sublattice are damaged or according to [1] only the zn-Lattice, a chemical assignment to the defect centers E4 and E3 could be accomplished.

Acceptor doping in ZnO with group-I elements
TL;DR: In this paper, the authors studied the interaction of hydrogen donors and Li acceptors in bulk ZnO by electron paramagnetic resonance and photoluminescence, and proposed a tentative model for the shallow Li acceptor whereby hydrogen would be an essential part of the defect core.

Incorporation of nitrogen acceptors in ZnO powder
TL;DR: In this paper, the preparation and characterization of N-doped ZnO powders were described. But the authors did not report on the N-acceptors in single crystals.
