Currently nano- rare earth luminescent materials research in the field of materials science is one of the hotspots , and has broad application prospects. Lanthanum molybdate is an important functional material , it not only can be used as catalyst for the fast ion conductor used in many fields, but also has good stability and efficient energy transfer , etc., makes it an excellent matrix material glowing . Therefore, using electrospinning preparation of rare earth ions doped La2Mo2O9 Low-dimensional light-emitting materials will be a meaningful and important research topic . In this article polyvinylpyrrolidone and metal nitrates as precursors by the sol - gel process prepared with a certain viscosity precursor sol , and were prepared using electrospinning PVP / nitrate composite fibers and composite nanoribbons , after heat treatment was La2Mo2O9, La2Mo2O9: Eu3, La2Mo2O9: Tb3, La2Mo2O9: Sm3, La2Mo2O9: Er3, La2Mo2O9: Nd3, La2Mo2O9: Pr3 nanofibers and porous nanoribbons using TG-DTA, XRD, FTIR, FESEM, TEM and fluorescence spectroscopy techniques were used to characterize the samples . The results showed that the prepared rare earth ions doped La2Mo2O9 nanofibers uniform size , and there are no cross-linking , the average fiber diameter of 180-220 nm, length greater than 100μm. The preparation of rare earth ions doped La2Mo2O9 nanoribbons porous structure , generous ratio, average bandwidth 5-7μm, a thickness of about 130-280 nm, length greater than 500μm. Obtained some interesting findings for the further study of rare earth doped La2Mo2O9 luminescent properties of nanomaterials laid a certain foundation.
