Title:

光電面、それを備える電子管及び光電面の製造方法

Document Type and Number:

Japanese Patent JP4926504

Kind Code:

B2

Abstract:

A photoelectric element 10 includes a substrate 12 that transmits incident light, an intermediate layer 14 made of HfO 2 , an under layer 16, and a photoelectron emitting layer 18 containing an alkali metal. That is, the photoelectric element 10 includes the intermediate layer 14 formed between the substrate 12 and the photoelectron emitting layer 18. Thereby, a photoelectric element that can exhibit a high value of effective quantum efficiency, an electron tube including the same, and a method for producing a photoelectric element are realized.
