ELECTRON SOURCE, MANUFACTURING METHOD THEREOF, AND DISCHARGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide: an electron source that achieves electron emission at low voltage, stable operation and high reliability; a method for manufacturing the electron source; and a discharge device such as a cold cathode discharge lamp using the electron source.

SOLUTION: An electron source 1 has a substrate 2, an aggregate of diamond crystal particles 3 that is formed on the substrate 2, and platinum particles 4 formed on the top surface of the diamond crystal particles 3. The electron source 1 is used for a discharge device such as a cold cathode discharge lamp.
