Abstract

본 발명은 안료부착 형광체의 제조방법에 관한 것으로서, 형광체의 표면에 바인더를 사용하여 안료를 부착하여 제조되는 안료부착 형광체의 제조방법에 있어서, 상기 안료부착 형광체가 안료 미부착 형광체가 안료부착 형광체를 혼합하여 얻어지는 것을 특징으로 하는 안료부착 형광체의 제조방법을 제공한다. 본 발명의 안료부착 형광체는 휘도와 색순도가 향상된 우수한 안료부착 형광체이다.The present invention relates to a method for producing a pigment with phosphor, wherein a method for producing a pigment with phosphor prepared by attaching a pigment to a surface of the phosphor using a binder, wherein the pigment without phosphor is mixed with a pigment without phosphor It is obtained by providing a method for producing a pigment-containing phosphor characterized in that. The pigmented phosphor of the present invention is an excellent pigmented phosphor with improved brightness and color purity.
