摘　　要：以AgNO3和NH4VO3为原料,采用水热法制备了α-AgVO3微米棒。采用X射线衍射(XRD)和场发射扫描电子显微镜(FE-SEM)对样品的结构和表面形貌进行了表征。紫外-可见漫反射测试(UV-vis DRS)显示α-AgVO3微米棒具有较宽的紫外-可见光吸收范围,计算得出α-AgVO3微米棒的光学带隙为2.54 eV。Using AgNO3 and NH4VO3 as raw materials,α-AgVO3 microrods were fabricated by hydrothermal process.The structure and morphologies of the products were characterized by X-ray diffraction（XRD） and field-emission scanning electron microscopy（FE-SEM）.UV-visible diffuse reflectance spectrum（UV-vis DRS） shows that the as-prepared α-AgVO3 microrods present strong absorption in a wide range from UV to visible light and the band gap was measured to be 2.54 eV.
