The particle size of YAG:Ce phosphors for light-emitting diode (LED) was controlled by gravitational sedimentation, and their photoluminescence properties were investigated. The morphology, particle size and crystallite structure were characterized by scanning electron microscopy, laser particle sizer, and X-ray diffraction and the photoluminescence (PL) properties were examined by spectrophotometer and LED photo-color and electron test systems. The results revealed that the obtained samples have a very smooth surface and nearly spherical shapes with a uniform size, which can be effectively controlled, and their PL properties are strongly dependent on particle size. The PL intensity of samples increases with the increasing of particle size for particle size less than 11.0 μm. In contrast, the PL intensities decrease with the increasing of particle size, when the particle size is larger than 11.0 μm. Therefore, the optimized size of phosphor is 11.0 μm, showing a great potential for LED application.
