本文对锑铯阴极光电疲乏过程的电化学特性作了叙述。引氧敏化过程,作出了紫外与可见光灵敏度的变化曲线,并在金相显微镜下观察到SbCs与SbCsO的不同外貌。文章还叙述了碲铯阴极的光谱响应特性。并在制造工艺过程证实Cs<2Te>1光电发射的日盲性。附有阴极不同组成时Cs2Te.CsTe与Cs3Te2的三种金相外貌照片。最后,提供出适用于这两种光阴极的量子效率的计算公式。众所周知,锑铯阴极对近紫外线与可见光有高的灵敏度、碲铯阴极则对中紫外线很灵敏。两种阴极在光电器件中的应用极为广泛。我们对此两种阴极某些性质作了研究,今介绍如下。
This article describes the electrochemical characteristics of antimony cesium cathode photoelectrical fatigue process. In the process of oxygen-sensitization, the curves of UV-vis and visible light sensitivities were obtained, and the different appearances of SbCs and SbCsO were observed under a metallographic microscope. The article also describes the spectral response of tellurium cesium cathode. And in the manufacturing process confirmed Cs <2Te> 1 solar eclipse blindness. Three metallographic appearances of Cs2Te.CsTe and Cs3Te2 with different cathode compositions. Finally, the calculation formulas for the quantum efficiency of the two photocathodes are provided. As we all know, antimony cesium cathode near UV and visible light with high sensitivity, tellurium cesium cathode UV is very sensitive. The two cathodes are extremely versatile in optoelectronic devices. We have done some research on some of the properties of these two cathodes, and are introduced below.
