摘要：

Optically detected magnetic resonance shows that a broad, green emission band in ZnO at 2.45 eV originates from a spintriplet-recombination characterised by g(parallel toc) = 1.984 and g(perpendicular toc) = 2.025 (parallel and perpendicular to the crystallographic c-axis, respectively) and a zero-field splitting of D = 260 x 10(-4)cm(-1). These parameters and the polarisation properties of the emission are very similar to the anion vacancies in CaO but not compatible with the Zeeman results on ZnO:Cu. (C) 2001 Elsevier Science B.V.
