Phosphorescence in cooled organic materials—temporal kinetics and spectral memory effect

Abstract

Abstract The results are presented of the study of long-term phosphorescence in solid solutions of materials at cryogenic temperatures. In this way we continue the series of our works devoted to studying the physical mechanism of excitation of the long-term phosphorescence and prospects for creating effective laser media based on an analogue of the Shpolsky matrix. The earlier unknown effect of spectral memory in solids is discovered to occur in organic solutions in response for excitation of phosphorescence by the mercury-lamp radiation.
