PROCESS FOR PRODUCING PHOSPHOR AND PLASMA DISPLAY PANEL UNIT |
摘要 |
Fine particles of a phosphor are weighed, mixed, and filled. Provided after this step are at least one step of firing the particles in a reducing atmosphere, and a step of pulverizing, dispersing, rinsing, drying and then performing oxygen ion implantation treatment for implanting oxygen ions and annealing the particles, after the step of treatment in the reducing atmosphere. This method recovers oxygen vacancy in the host crystal of the phosphor. <IMAGE> |
