Abstract: Lanthanum orthovanadate nanorods were synthes ised by a template - directing hydrothermal method.and were characterized by XRD,SEM,TEM and photoluminescence (PL) technique. The results show that the as - synthes ised products are pure s ingle - crys tal LaVO4 nanorods with tetragonal zircon - type s tructure, The products cons is t mainly of lanthanum orthovanadate nanorods with length of 1~2μm and diameter of 80~120 nm. Compared with LaVO4 nanoparticles ,the LaVO4 nanorods has better luminescent properties .Meanwhile,the tetragonal phase LaVO4 nanorods has better luminescent properties than monoclinic phase LaVO4 nanoparticles .
