英文摘要：

Fe3O4-[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O（L= pyridine-2-carboxamide）composite nanoparticles were successfully synthesized by Fe3O4and[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O.Fe3O4 nanoparticles were synthesized via non-aqueous nanoemulsion method using the triblock copolymer poly（ethylene oxide）-poly（propylene oxide）-poly（ethylene oxide）（PEO-PPO-PEO）as the surfactant,iron（II acetylacetonate（Fe（acac）2）as precursors,1,2-hexadecanediol as the reducing agent.The morphology of the Fe3O4-[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O composite nanoparticles was analyzed by transmission electron microscopy（TEM）.The Fe3O4-[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O composite nanoparticles are virtually uniform and nearly spherical in shape with an average diameter about 10.4nm and a narrow size distribution.The structures of the Fe3O4-[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O composite nanoparticles were confirmed by X-ray powder diffraction（XRD）.The Fourier transform infrared spectroscopy（FT-IR）further shows the formation of the Fe3O4-[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O composite nanoparticles.The optical properties of the Fe3O4-[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O composite nanoparticles were investigated using an ultraviolet-visible spectrophotometer（UV-Vis）and a photoluminescence spectrophotometer（PL）.The UV-Vis spectrum of Fe3O4-[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O shows two well-behaved absorption bands locating at 217nm and 227nm from [（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O.The PL emission spectrum reveals that the Fe3O4-[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O composite nanoparticles manifest a visible fingerprint photoluminescent emission at413nm.The magnetic properties of the Fe3O4-[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O composite nanoparticles were studied by a vibrating sample magnetometer（VSM）.The hysteresis curve acquired clearly shows that the Fe3O4-[（ZnL2）（H2O）2]2H2[P2Mo5O23]·2H2O composite nanoparticles are soft ferromagn
