Abstract

A study of the visible photoluminescence in single-crystal NiO and Ni _cMg_1-cO (c=0.99, 0.98 and 0.95) solid solutions is presented for the first time. Two wide luminescence bands, peaked at ∼12000 cm^-1 and ∼18500 cm^-1, were observed. The dependence of their intensity and position on the excitation energy, temperature, and composition were investigated. We attribute the origin of two photoluminescence bands to the impurity- or defect-perturbed Ni²⁺ excitons.
