Description
Highlights: ► YVO4 nanowire were synthesized by chemical precipitation in AAO. ► All of nanowires in uniform diameter are parallelly arranged. ► YVO4 nanowires mainly consist of polycrystalline materials. ► YVO4:Eu nanowires are luminescent under electron excitation. -- Abstract: Monodisperse nanowires and arrays of YVO4:Eu3+ were synthesized by chemical precipitation method using anodic aluminum oxide template. Scanning electron microscope images indicated that YVO4:Eu3+ 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 YVO4:Eu3+ nanowires mainly consist of polycrystalline materials. Excitation and emission spectra of YVO4:Eu3+ composite films were measured. The characteristic red emission peak of Eu3+ ion attributed to the 5D0–7F2 transition in YVO4:Eu3+ nanowires broadened its half width.
