Abstract: Eu3+-doped LaPO4 micro-nanofiberswere prepared by the electro spinning technology. Scanning electron microscope(SEM), X-ray diffraction (XRD), the mogravimetry-differential thermal analysis(TG-DTA), and photoluminescencespectra (PL) were used to characterize the obtained samples. XRD patterns indicate that theas-prepared micro-nanofibers are crystallized well at 800℃ and assign edto JCPDS-35-0731 of the monoclinic LaPO4 crystal. Upon excitation into the Eu3+ at 409 nm, the emission spectrum of LaPO4:Eu3+ micro-nanofibers is composed of 5 D0- 7 F J (J = 1, 2, 3, 4) emission lines of Eu3+, with the transition 5 D0 - 7 F2 (at 618 nm) being the most prominent group, which is characterized by red emission. The optimum doping concentration of Eu3+ is 5mol% in the LaPO4: Eu3+ micro-nanofibers. The luminescence decay curve of LaPO4: Eu3+ micro-nano fibers shows single exponential behavior, and the lifetime(τ) of Eu3+ is about 3.7 ms.
