Abstract. The luminescence properties of the Rodamine 6G in strongly scattering matrix in dependence of the medium parameters were examined. The luminescence spectrum of this object was found to be dependent on the scattering particle concentration, particle material and sample thickness. It was shown that the main reason of the dependencies is an enhanced reabsorption of luminescence radiation in the light scattering sample caused by manifold light scattering.

Keywords: multiple light scattering, reabsorption, luminescence, dye, polymer, rhodamine 6G.
