摘要：

A facile and mild hydrothermal approach has been developed to prepare hollow t-LaVO4:Eu3+ nanospheres in Eu(NO3)(2) aqueous solution with solid LaCl3 center dot 7H(2)O and Na3VO4 as raw materials. The structure, morphology, composition and thermal behavior of LaVO4:Eu3+ nanospheres were studied by an X-ray diffractometer (XRD), a scanning electron microscope (SEM), an energy dispersive X-ray spectrometer instrument (EDS), a Fourier transform infrared spectrometer (FT-IR) and a differential thermal-thermogravimetric analyzer (DTA-TG). LaVO4:Eu3+ nanospheres hollow gradually with the increasing reaction time owing to Kirkendall effect. And hollow t-LaVO4:Eu3+ nanospheres show excellent red luminescence under 300 nm excitation, which could be of potential use in fabricating red-emitting nanolasers. (C) 2015 Elsevier B.V.
