Highlights: Black-Right-Pointing-Pointer YVO{sub 4} nanowire were synthesized by chemical precipitation in AAO. Black-Right-Pointing-Pointer All of nanowires in uniform diameter are parallelly arranged. Black-Right-Pointing-Pointer YVO{sub 4} nanowires mainly consist of polycrystalline materials. Black-Right-Pointing-Pointer YVO{sub 4}:Eu nanowires are luminescent under electron excitation. -- Abstract: Monodisperse nanowires and arrays of YVO{sub 4}:Eu{sup 3+} were synthesized by chemical precipitation method using anodic aluminum oxide template. Scanning electron microscope images indicated that YVO{sub 4}:Eu{sup 3+} nanowires are parallelly arranged, all of which are in uniform diameter of about 50 nm. High-magnification transmission electron microscopy images showed that the nanowires are composed of a lot of agglutinating particles. X-ray diffraction patterns confirmed that YVO{sub 4}:Eu{sup 3+} nanowires mainly consist of polycrystalline materials. Excitation and emission spectra of YVO{sub 4}:Eu{sup 3+} composite films were measured. The characteristic red emission peak of Eu{sup 3+} ion attributed to the {sup 5}D{sub 0}-{sup 7}F{sub 2} transition in YVO{sub 4}:Eu{sup 3+} nanowires broadened its half width.
