Europium thenoyltrifluoroacetone coordination polymer(Eu-CP)nanoparticles have been prepared via a facile solvothermal method employing Eu(NO 3)3·6H 2O as metal ion source,and thiophene-formyl trifluoroacetone as organic ligand.In order to study the structure and composition of precursors,a series of characterizations of the precursors are performed and their luminescence properties are studied.In addition,a series of spin-coating films of Eu-CP nanoparticles with different raw material ratios are prepared by mixing with polymethyl methacrylate and using N,N-dimethylformamide as solvent.And their fluorescence intensities are compared.Furthermore,the light stability and thermal stability of the films obtained are also investigated.
