Title:
PHOTOELECTRIC SURFACE, ELECTRON TUBE COMPRISING SAME, AND METHOD FOR PRODUCING PHOTOELECTRIC SURFACE
Document Type and Number:
WIPO Patent Application WO/2007/102471
Kind Code:
A1
Abstract:
Disclosed is a photoelectric surface wherein the quantum efficiency is improved.
Specifically disclosed is a photoelectric surface (10) comprising a light transmissive
substrate (12) composed of a quartz glass or a borosilicate glass, an intermediate
layer (14) composed of hafnium oxide (HfO2), a foundation layer (16)
composed of an oxide of manganese, magnesium or titanium, and a photoelectron-emitting
layer (18) composed of a compound of an alkali metal and antimony. The intermediate
layer composed of hafnium oxide prevents the alkali metal contained in the photoelectron-emitting
layer from moving into the light transmissive substrate, thereby contributing
to improvement of the quantum efficiency.
