| titleOfInvention | Cathode for Cathode Ray Tube |
| abstract | The present invention is a cathode including a cathode sleeve having a heater installed therein, a base metal supported by the cathode sleeve and formed on top of the cathode sleeve, and a hot electron emission layer supported by the base metal and formed on the base metal. In the structure, the hot electron emission layer relates to a cathode for a cathode ray tube, characterized in that consisting of alkaline earth metal oxide and yttrium-doped thorium oxide (Y 2 O 3 doped ThO 2 ), the generation and disappearance of free barium This stable operation provides a cathode for a cathode ray tube which prevents deterioration of the lifetime of the cathode. |
