After poling of the film, the refractive indices n t and n n, that is the in-film-plane and the normal-to-film-plane refractive indices at 633 nm and the thickness d were determined using the quasi-waveguide m -line method. The results of measurement and calculation are: n t=1.657 3±0.001 7, n n=1.627 8±0.001 9, and d =1.427 8±0.003 1 μm.展开更多

The result shows that this composite film has very high conductive properties, the maximum value of conductivity reaches 0.173 S/cm at the concentration 0.75 mol. The influences of HClO 4 on the conductivity of the composite film are investigated.In addition,the electrode reaction progress is discussed with the result that obtained from SEM and FTIR analyzing.展开更多
