INFLUENCE OF THE EXCITATION LIGHT INTENSITY ON THE CONCENTRATION DEPENDENCE OF ORGANIC MOLECULES LUMINESCENCE IN GLASSY MATRICES
Abstract
The population distribution of the molecules on triplet level in a glassy solution of organic compounds at different intensity of the excitation light and several concentrations has been investigated by computer simulation. The dependence of the triplet level population distribution on these quantities was found. It was shown that the effect of the excitation light intensity on the concentration dependence of the luminescence intensity is a consequence of the found relationship between these quantities, when the change of the population of the ground state of molecules as a result of transition of molecules to the triplet state cannot be neglected.
