Phosphor, method for producing the same, and plasma display panel using the phosphor |
| abstract |
In a europium (Eu) activated phosphor, particularly a blue phosphor, wavelength conversion efficiency is kept high and deterioration with time due to vacuum ultraviolet light is reduced. In addition, the image sticking phenomenon of the plasma display panel due to the temporal deterioration of the phosphor is prevented. The concentration distribution of Eu in the phosphor particles is higher in the vicinity of the particle surface (from the surface to a depth of about 10 nm) than the whole particle, and the divalent Eu ratio in the total Eu contained in the phosphor particles is The Eu-activated alkaline earth metal aluminate phosphor is lower in the vicinity of the particle surface than the entire phosphor particles. By using this phosphor as a blue phosphor of a plasma display panel, a burn-in phenomenon due to deterioration with time can be prevented. [Selection] Figure 1 |
