The complex Sm(OPri)(TTA)2 was synthesized

and the Sm(OPri)(TTA)2／PMMA photoluminescent polymer was prepared by coordination bulk polymerization of rare earth complex and methyl methacrylate(MMA)．The complex and polymer have been characterized by FT-IR

1H-NMR

XRD

dynamical mechanical thermal analysis (DMTA)

FS and ESEM etc．The results show that the Sm(OPri)(TTA)2／PMMA exhibits strong characteristic luminescence of samarium ion4G5/2→6H5/2

4G5/2→6H9/2 at 562

598

644 nm respectively under excitation with radiation of 396 nm and its luminescent strength is as high as that of Sm(TTA)3／PMMA．Moreover the storage modulus(E')

glass transition temperature(Tg)and viscous flow temperature(Tf)of the polymer are higher than those of PMMA．DMTA indicates that Sm(OPri)3／PMMA shows a crosslinking structure

whereas Sm (OPti)(TTA)2／PMMA shows a linear structure．
