The invention relates to a surface disposal method of an
ultraviolet excitation red fluorescent
powder, belonging to the field of inorganic synthesis technique of optical function material. The method comprises the steps as follows: the surfactant
raw material is screened by a screen of 400 meshes and ball-grinded; subsequently, the consistency of the solution is adjusted and the solution is mixed to
gain the surfactant; subsequently, according to the
mass percentage in occupation to
yttrium europium oxide, 0.005-0.05 percent of surfactant is added into the red fluorescent
powder of the
yttrium europium oxide; under a mixing state, the surfactant and the red fluorescent
powder of the
yttrium europium oxide are mixed; the mixture is dehydrated, dried and screened, thus gaining the red fluorescent powder of the yttrium europium oxide with the surface disposed, wherein, according to the
mass percentage, the surfactant is one of 5-20 percent Gama-Al2O3 solution, yttrium oxide,
potassium silicate,
zinc silicate or
zinc sulfate. The surface disposal method can prepare the commercial red fluorescent powders which has good powder fluidity, good
coating performance, good dispersion performance and good
luminescence. The prepared red fluorescent powder of the yttrium europium oxide has the advantages of good fluidity, good
coating performance, good dispersion performance and good
luminescence.
