Abstract: The present invention provides a phosphor of white LED and the manufacturing method of the same, relating to a phosphor of light-emitting material, and more particularly to a high-efficiency phosphor of semiconductor white light emitting diode in sphericized or director-sphericized crystal structure. The general formula (Y1-xGdx)3-z(Al1-yGay)5O12:Cez3+, therein 0?x?0.45 mol/mol, 0?y?0.55 mol/mol, 0.06?x?0.12 mol/mol, the sensitizer includes rare sensitizer Ce3+ and other aid-sensitizers, where said aid-sensitizer is at least one of Pr, Th, Dy and so on, the concentration of Pr, or Tb, or Dy is individually 5%˜10% of the Ce3+'s.
