Due to the excellent properties such as lightness,good transparency,impact resistance,processability,and dyeability,optical resins were extending their application as transparent materials replacing inorganic optical materials in wide fields.Rare earth compleses with organic ligands,especially those containing Er\+\{3+\} and Tb 3+ ,often exhibit efficient luminescence such as high luminous intensity,long luminous lifetime and sharp line spectrum. Though rare earth complexes assumed sound luminescence performance,but the stability was different ,as a result,its application was restraint.If rare earth complexes were recombined into a range of suitable cuchion substance,the cushion substance can provied relatively stable environment for the rare earth complexes,which is good to exihbit the luminescent characteristic of the rare earth complexes.Furthermore,the rare earth complexes can offer the cushion substance novel function. According to the principle of molecular design,when introducing rare earth ion into the optical resin,the transparent polymer with luminescent properties could be prepared.In our knowledge,this research has rarely been seen before and is terrifically significantly. In this paper,the rare earth complexes were combined into optical resins,and the resins that possess high transparency and good luminescent properties were obtained,their optical properties were studied.In addition,the relationships between the transparency luminescent properties of the polymer and the content of the components in the copolymer system were investigated.
