photocathode 是什么意思

中文翻译与英英解释

n.
【物理学】光阴极,光电阴极。
a cathode that emits electrons when illuminated

A photocathode is a negatively charged electrode in a light detection device such as a photomultiplier or phototube that is coated with a photosensitive compound. When this is struck by a quantum of light (photon), the absorbed energy causes electron emission due to the photoelectric effect.
