Study of photophysical properties of composite materials based on polystyrene, polymethyl methacrylate, and Eu(III) complex with 1-(1,5-dimethyl-1h-pyrazole-4-yl)-4,4,4-trifluorobutane-1,3-dion and 1,10-phenanthroline

The effect of the polymer matrix on luminescence properties of the europium complex we synthesized is studied. It is shown that the interaction of complex molecules with the matrix has practically no effect on the photoluminescence spectrum shape. The excited state lifetime decreases no more than twice.
