Abstract
The effect of gadolinium on the luminescence of europium in mixed complexes with thenoyltrifluoroacetylacetone and 1,10-phenanthroline in poly(methyl methacrylate) and polyethylene films has been studied. The scale of change in light resistance with varying the proportion of gadolinium and the concentration of the complex in the polymer has been estimated. An increase in the relative intensity of luminescence in polyethylene with an increase in the proportion of gadolinium in the complexes has been revealed, themagnitude of which corresponds to a similar effect for complexes in the crystalline state. This effect is absent in poly(methyl methacrylate) films; however, the presence of gadolinium lowers the rate of decrease in luminescence intensity during photolysis.
