摘要：
The steps of weighing, mixing and filling for phosphor powder are followed by the reducing atmosphere treating step wherein treating in a reducing atmosphere is carried out at least once and, after the reducing atmosphere treating step, pulverization, dispersion, water washing and drying and further the oxygen ion implantation treating step wherein oxygen ion implantation and annealing are performed, so that host crystals are restored with respect to oxygen defects.
