PROBLEM TO BE SOLVED: To obtain a resin compsn. excellent in luminous characteristics by incorporating a rare earth complex into a polymer matrix. SOLUTION: This compsn. comprises 0.001-20 wt.% rare earth complex and 99. 999-80 wt.% polymer (e.g. a polymethacrylate). This compsn. in an amt. of 100 pts.wt. can be mixed with 0-2,000 pts.wt. polar solvent (e.g. dimethyl sulfoxide). The rare earth complexes represented by formulas I, II, and III are prepd. by mixing the corresponding ligands with at least one rare earth metal compd. selected from rare earth metal oxides, rare earth metal hydroxides, rare earth metal alkoxides, rare earth metal amides, and rare earth metal salts, In the formulas, M is a rare earth atom; Rf1 to Rf3 are each a hydrogen-free 1-22C aliph. group, an arom. group or the like; X1 and X2 are each a group-IVA atom, a group VA atom (except nitrogen) or the like; X3 is a group-IVA atom (except carbon), a group-VA atom (except nitrogen) or the like; Y is C-Z1 (wherein Z1 is dertorium, halogen or the like), N, P or the like; n1 is 2 or 3; n2 is 2-4; and n5 is 0, 1 or the like.
