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 treating the particles in an ozone atmosphere after the last step of treatment in the reducing atmosphere. This method recovers oxygen vacancy in the host crystal of the phosphor.
