PURPOSE: A producing method of YAG:Ce phosphor powder is provided to apply the powder having excellent color rendering property to a light emitting diode. CONSTITUTION: A producing method of YAG:Ce phosphor powder comprises the following steps: preparing a mixed solution containing yttrium, cerium, and aluminum(S1); producing a solution with a precursor by adding the mixed solution in a precipitation agent using a dripping method(S2); aging the solution with the precursor, filtering the outcome to obtain a precipitate, and washing the precipitate with distilled water(S3); and calcinating the precipitate at 1,000-1,300 deg C(S4). |
