Some Special Features of the Concentration Dependence of the Quasi-Line Spectrum Intensity

The nonlinearity mechanisms of the concentration dependence of the quasi-line spectrum intensity are investigated for 1,2-benzpyrene in n-hexane. It is established that redistribution of molecules over the energy levels, caused by the effect of internal filter created by substituted impurity molecules, can contribute significantly to changes in the spectrum intensity. It is demonstrated that this effect can cause redistribution of the quasi-line luminescence spectrum intensity for a multicomponent system.__________Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 4, pp. 3–6, April, 2005.
