The investigation of the processes occurring on their surfaces in the presence of a well-spread, oxygen-containing gaseous medium using luminescence methods is relevant. This article presents data on the patterns of chemiluminescence excitation in the Y3O2:Bi3+ crystalline phosphorus in the nitrous oxide (N2 O) flow. The kinetic, temperature and spectral characteristics of the chemiluminescence were studied. A gradual mechanism of chemiluminescence excitation was studied. The practical value of this study is that its results can be used to develop fundamentally new luminescent methods for the qualitative and quantitative determination of oxygen-containing impurities in gases and to prepare monographs and teaching aids in chemical physics.
