| 中文摘要 | Bismuth molybdate films with various phase structures including alpha-Bi(2)Mo(3)O(12), beta-Bi(2)Mo(2)O(9), gamma-Bi(2)MoO(6), and gamma'-Bi(2)MoO(6) are fabricated on the indium-tin oxide glass substrates from an amorphous heteronuclear complex via the dip-coating method by appropriate adjustment of the reaction conditions. alpha-Bi(2)Mo(3)O(12), beta-Bi(2)Mo(2)O(9), and gamma-Bi(2)MoO(6) film can be obtained at 400 degrees C, 500 degrees C, and 500 degrees C for 1 h, respectively. At 500 degrees C, gamma'-Bi(2)MoO(6) can be obtained for 4 h. Film formation process is proposed based on the experimental results. Thin gamma'-Bi(2)MoO(6) films exhibit high photoresponse under visible light irradiation. incident photon to current conversion efficiency of thin gamma'-Bi(2)MoO(6) film starts to increase near 450 nm. And, it can reach 4.1% at 400 nm. The top of the valence band and bottom of the conduction band are roughly estimated to be -0.71 and 1.69 ev, respectively. In contrast, gamma'-Bi(2)MoO(6) generated weak photocurrent; alpha-Bi(2)Mo(3)O(12) and beta-Bi(2)Mo(2)O(9) film has no photoresponse under visible light irradiation. The reason for the difference in the visible light response was discussed. (C) 2009 Published by Elsevier B.V. |
