摘要:
Disclosed here is a plasma display unit that employs phosphors having an amount of charge controlled close to zero, by which degradation in luminance, color temperature, and charge characteristics can be minimized. A phosphor bearing positive or negative charge is coated with a compound for controlling the amount of charge of the phosphor through a strong chemical bonding, whereby the amount of charge of a phosphor can be suppressed within ±0.01 μC/g. Controlling the amount of charge of phosphors close to zero can keep impurity gases away from the phosphor particle when the panel is in operation, suppressing problems critical to driving a plasma display unit, such as luminance degradation of phosphors, improper alignment of color in panel operation, luminance degradation when the panel displays all white.

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.
