| 摘 要： | 用溶胶凝胶的方法在ITO导电基片上制备了一组不同掺镍量的氧化钨钼薄膜,分别测量了该系统及ITO电极浸泡于1 mol氯化钠溶液中不同频率下的电化学阻抗,应用等效电路法模拟了该系统的阻抗谱,从而获得了有关掺镍薄膜的电阻、电容及溶液在薄膜内扩散等信息.研究表明,与ITO电极所产生的吸附层的等效元件参数相比较,掺镍氧化钨钼薄膜大大提高了ITO电极传输电荷的能力.

| Abstract: | The Ni doped WO3-MoO3 films were prepared by the sol-gel process.The electrochemistry impedance spectroscopies of ITO plane electrodes and ITO plane electrodes with Ni doped WO3-MoO3 thin film immersed in 1 mol NaCl electrolyte were studied by means of the equivalent circuits.The characteristics of the constant phase angle elements,the capacitance and resistance and solution diffusion resistance in Ni doped WO3-MoO3 thin films were gained.The results show that the effect of adsorption layer on ITO electrode... |
