Abstract
We have experimentally investigated the dependence of the luminescence intensity of ethanol solutions of 2-(4-pyridyl)-5-phenyloxazole on the intensity of the exciting radiation from an XeCl laser (λex = 308 nm, τp = 10 nsec, Eex=1022–1026 photons/cm2·sec). We discuss the measurement technique and possible reasons for the change in radiative properties of the investigated solutions under the given conditions.
