RT Journal Article T1 Cathodoluminescence and photoluminescence spectroscopy of NiO A1 Díaz-Guerra Viejo, Carlos A1 Remon, A. A1 García, J. A. A1 Piqueras De Noriega, Francisco Javier AB Cathodoluminescence (CL) and photoluminescence (PL) of nickel oxide (NiO) have been investigated. 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.
