Abstract:: The paper presents the results of delayed phosphorescence study in organic substances solid solutions at cryogenic temperatures. This work continues the series of our works devoted to the study of the physical mechanism of excitation of long-term phosphorescence and the prospects for creating new active laser media based on an analogue of the Shpolsky matrix. The article also describes the observed effect of spectral memory in solid organic solutions upon excitation of long-term delayed phosphorescence by radiation from a mercury lamp.

Keywords: Long-term phosphorescence, organic compounds, cryogenic temperature, Shpolsky matrix, solid solutions, spectral memory effect
