摘要

本文导出了半透明光电阴极的量子产额公式。光电阴极的量子产额可以用体积函数和表面函数来表示

当Na

KSb光电阴极用铯（Cs）激活时

不仅改变了有效电子亲和势

而且改变了光电子的逸出深度。

Abstract

A formula of quantum yield is derived for semitransparent photocathode in this paper. The quantum yield of the photocathode is represented by volume function and surface function. When photocathode Na2KSb is activated by Cs

it is not only to change efficient electron affinity but also change depth of escaping electrons.
