γ-irradiation effects on the luminescence decay in benz(f)indan and anthracene doped fluorene single crystals

Abstract

Information on the effect of γ-irradiation on the emission behaviour of dopants benz(f)indan and anthracene in a single crystal of fluorene is presented. Quenching is of the Stern-Volmer type at low doses (up to 10.6 Mrad) but the effect tends to saturate at higher doses. The same quenching parameter for the irradiation products is found for benz(f)indan and anthracene.
