titleOfInvention | Photocathode for photomultiplier, preparation method and photomultiplier |
abstract | The invention relates to the technical field of photomultiplier tubes, and provides a photocathode for a photomultiplier tube, a preparation method and the photomultiplier tube. Preparing a basal layer on the inner side surface of a glass optical window of the photomultiplier, wherein the basal layer is made of Al 2 O 3 Forming a crystalline material of (a); a bi-alkaline photocathode is prepared on a base layer, wherein the base layer is in contact with both the bi-alkaline photocathode. Thus, the present invention employs Al in the photocathode 2 O 3 The basal layer is used as an antireflection film, so that the probability of light incidence to the photocathode is effectively increased, and the quantum efficiency of the photocathode is improved; at the same time, Al 2 O 3 The substrate layer has certain conductivity, and can rapidly supplement electrons of the photocathode which are lacked due to the photoelectric effect, so that the quantum efficiency is further improved. |
