Title:
PHOTOELECTRIC CATHODE, METHOD OF PRODUCING SAME AND PHOTOMULTIPLIER WITH SAME CATHODE
Document Type and Number:
Japanese Patent JPS5755048
Kind Code:
A
Abstract:
Photocathode of SbK2Cs destined for any electro-optical tube. Photocathode (11) comprising a layer (12) of potassium and caesium antimonide SbK2Cs deposited on the substrate (13), also comprising a sub-layer (14) of manganese oxide, intermediate between the said substrate (13) and the said layer (12) of SbK2Cs, the said sub-layer (14) of MnO improving in the red the spectral sensitivity of the layer (12) of SbK2Cs. Application notably for photomultiplier tubes used in nuclear physics.
