PHOSPHOR PRECURSOR MANUFACTURING METHOD

摘要

Provided is a phosphor precursor manufacturing method wherein discretionary doping of a dopant having a large ion radius can be performed so as to manufacture phosphor for providing high luminance and high energy efficiency. In the phosphor precursor manufacturing method, a phosphor base material is doped with the dopant, under existence of a particle growth accelerator operating also as dopant, by applying an impact pressure of 0.1GPa or more to a mixture composed of the phosphor base material, the dopant and the particle growth accelerator operating also as dopant.
