Cathode with an electron emitting layer for a cathode ray tube |
| abstract |
A cathode for a cathode ray tube includes a base having a closed top portion and containing nickel as its main component, an electron-emitting material layer coated on the top portion of the base and containing alkali-earth metal oxides as its main component, rare-earth metals or rare-earth metal compounds attached on a surface of the electron-emitting material layer, and a heater placed under the top portion of the base to heat it. |
