The observed emission bands in the visible and near infrared spectral ranges are attributed to Ni^(2+) intraionic transitions. Some of the features observed in the CL spectra recorded from vacuum annealed samples are tentatively attributed to electronic transitions involving defect-induced states located inside the charge-transfer gap of this transition metal oxide.journal articlehttp://dx.doi.org/10.1002/1521-396X(199710)163:2<497::AID-PSSA497>3.0.CO;2-Zhttp://onlinelibrary.wiley.commetadata only access538.9Electronic-StructureOptical-AbsorptionNickel-OxideNio(100)TemperatureExcitationsGapFísica de materiales
