Micro-sized complex of [Sm(Pic)2(H2O)(EO4)](Pic).H2O (where EO4 = tetraethylene glycol, Pic = picrate anion) and its micro-sized polymethyl methacrylate (PMMA) composite have been synthesized by one step (in-situ method) and three steps (reprecipitation-evaporation) methods. Fluorescence intensity of ion Sm3+ ion in the Sm-Pic- EO4/PMMA micro-sized composite is higher than that in the Sm-Pic-EO4 micro-sized complex. The composite is potential to be applied as a luminescent center in organic light emitting devices for bright-orange emission coming from Sm3+ ions .
