摘　　要：用喷雾法制备了 Sn O2 ∶ F膜光透电极 ,其在可见光区的透光率与导电性能等均符合光谱电化学研究的要求 ,并且具有较宽的电位适用范围和较好的化学稳定性。用光谱恒电位技术和循环伏安法测定了铁氰化钾 /亚铁氰化钾体系的克式量电位 E0 ′和电子转移数 n,获得了较好的重现性。SnO 2∶F thin film optical transparent electrode(OTE)was prepared by spary technique.The SnO 2∶F thin film OTE obtained exhibits good optical transparency,electrical conductivity as well as wide potential window and excellent chemical stability.A new kind of opticaly transparent cell was assembled for spectroelectrochemical investigation. The formal potential and electron transfer number of the reduction of potassiam ferricyanide were investigated using spectropotentiostat and cyclic voltametry technique.The good reproducible results were obtained.
