Sm(DBM)3Phen and Nd(DBM)3Phen were synthesized as stable rare-earth complexes in polymer matrix. Polymethylmethacrylate (PMMA) containing these complexes was highly transparent but exhibited emission peaks in the visible and near-infrared ranges when excited by ultraviolet light. These emission peaks were attributed to energy transfer from excited DBM to rare-earth ions. To evaluate the potential of this material for use in planar solar spectrum converters, complex-doped PMMA layers were solution-casted on top of Si solar cells and their spectral responses were investigated.
