In this study, synthesis of yttrium aluminum garnet (YAG):Ce3+phosphor powders for white light emitting diodes was investigated by mechanical method using the attrition‐type mill with no external heating and no flux in dry phase. High mechanical energy input to the starting powder mixture of Y2O3, Al2O3and CeO2achieved the synthesis of YAG:Ce3+without any flux materials. X‐ray diffraction patterns of the processed powders after 5 min processing revealed the peaks of YAG were clearly identified. The maximum temperature of the mill chamber during the processing was 240℃. The YAG phosphor obtained by the mechanical method revealed the internal quantum yield of 65% in the case of the sample mechanically processed under a reducing atmosphere. The synthesized powder showed granule structure consisting of submicron size of YAG particles, which is better handling for the fabrication of light emitting diode devices.
