Role of copper in the green luminescence from ZnO crystals
TL;DR: In this paper, the structureless green emission in ZnO was shown to be associated with Cu2+ ions, and it was shown that the unstructured green emission (observed before the high-temperature anneal) is don...

Varistors based on polycrystalline ZnO:Cu
T. R. N. Kutty,N. Raghu +1 more
TL;DR: In this paper, the incorporation of Cu in the ZnO lattice is indicated from the electron probe microanalysis and the photoluminescence spectra, and the presence of positive charges leads to thinning of the depletion region, resulting in nonlinear characteristics.

Zeeman-effect of Cu2+-centers in II-VI-compounds
I. Broser,Udo Scherz,M. Wöhlecke +2 more
TL;DR: In this article, the fine structure of energy levels responsible for infrared luminescence of Cu2+-ions in II-VI-compounds, and corresponding g-values are calculated on the basis of the most general effective Hamiltonian.

Fine Structure of the Infrared Absorption and Emission Spectra of Cu 2+ in ZnS and CdS Crystals
I. Broser,H. Maier,H. J. Schulz +2 more
TL;DR: In this article, the near-infrared absorption and emission spectra of ZnS and CdS crystals recorded at low temperatures are found to exhibit a pronounced fine structure.

Erzeugung 'ultraroter' kupferzentren in ZnS durch kernzerfall von Zn65
I. Broser,K.-H. Franke +1 more
TL;DR: In this paper, it was beobachtet, dass der Anstieg der Kupferkonzentration in den Kristallen von einer merklichen Zunahme der bekannten Ultrarot-Emission von ZnS: Cu begleitet wird.
