Doped polymers with Ln(III) complexes:: simulation and control of light colors

Complexes of Eu(III) and Tb(III) were dispersed in polystyrene for the purpose of generating the primary red and green light colors, and simulating of the secondary yellow color. The polymer was doped with one or both complexes. Under ultraviolet excitation, the Eu(III) and Tb(III) complex-doped polymers, both solid state light emitters, generate the red and green colors, respectively. The Eu(III) and Tb(III) mixed complexes in the polymer present the characteristic emissions of the lanthanide ions, simulating the secondary yellow light color. (C) 2002 Elsevier Science B.V.
