可见光吸收可以认为是Bi3+6s2或Bi3+6s2和O2p的杂化轨道形成的价带向V3d导带的跃迁。谱形状陡峭表明BiVO4在可见光区的吸收是从禁带迁移的而不是从不纯态迁移的。从紫外-可见漫反射光谱的主要吸收边可以估算BiVO4的禁带宽度为2.4eV，说明生成的晶体主要为单斜相BiVO4。 [ Last edited by qingshaojun0823 on 2009-7-12 at 09:27 ] |

| Visible light absorption can be accounted for the transition of covalent band formed by Bi3+6s2 or Bi3+6s2 and O2p hybrid orbitals towards V3d. The sharp peaks on spectra showed that visible absorption of BiVO4 was transited from forbidden band instead of pure state. It can be estimated that the gap of forbidden band for BiVO4 was 2.4eV from UV-visible diffuse reflectance spectra of the main absorption sides, which means that the majority of the crystals formed was monoclinic BiVO4. |
