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 approximately 12000 cm^-1 and approximately 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.
