摘　　要：利用聚偏二氟乙烯(PVDF)热释电膜作为热传感器,本文首次独立设计了现场光热光谱研究用的电解池,对电解池的光热信息进行了理论分析,并用该法研究了碱性溶液中银电极表面氧化层的性质。从光谱的变化证实:Ag表面Ag_2O层的生成与循环伏安曲线上阳极电流增长(约0.22V)同步。类似情况亦发生在AgO层的生成过程。The electrochemical cell for in-situ photothermal spectroscopy measurement was designed for the first time independently. A polyvinylidene difluoride (PVDF) pyroelectric film was used as a thermosensor. The photothermal signal in the cell was analysed theoritically. The properties of oxide layers formed on Ag surface in alkline solution have been investigated by using such in-situ spectroelectrochemical method. From the change of spectra it was proved, that the Ag-2O layer is formed on Ag surface simultaneously while the anodic current increases on voltmmetry curve, as well as in the case for the formation of AgO layer.
