Phosphor having resistance to deterioration caused by ultraviolet rays, and gas discharge display device of which image quality is not readily deteriorated over time |
| 摘要 |
A manganese-activated zinc silicate phosphor according to the present invention satisfies 0<beta-alpha<=0.5 and 1.7<=beta, where a value alpha is a ratio of a number of zinc atoms to a number of silicon atoms in a surface region of a phosphor particle, including a surface of the phosphor particle and a vicinity thereof, and a value beta is a ratio of a number of zinc atoms to a number of silicon atoms in a whole of the phosphor particle.
