The Time Characteristics and Phosphorescence Spectra of Cooled Carbon-Containing Analogues of the Shpolsky Matrix

This paper presents the results of studies of the time and spectral characteristics of phosphorescence in organic compounds cooled to cryogenic temperatures. The data obtained after the analysis make it possible to propose a physical mechanism of excitation of long-term phosphorescence and assess the prospects for creating new active laser media (based on an analog of the Shpolsky matrix).
