摘要：
A self-propagating high-temperature synthesis of samples of the MgAl2O4 : Mn2+ luminophor has been carried out using the thermal effect of the reaction between aluminum and sodium perchlorate. Using energy dispersive analysis, the qualitative and quantitative composition of the luminophor has been established. To determine the degree of oxidation of manganese ions, the EPR spectra of the luminophor have been studied. The phase composition of the synthesis products has been established by X-ray diffraction, and the luminescent properties have been characterized by the excitation and emission spectra. The influence of the manganese content, as well as the Al : Al2O3 ratio in the charge, on the luminescent characteristics of the synthesized product has been studied.
