描述: We reported on the successful synthesis of the Nd：YAG （Nd：Y3Al5O12） nano-powders by using urea as the precipitant with the microwave assisted homogeneous precipitation （MAHP） method. The different microstructural characteristics of the Nd：YAG nano-powders were affected by the concentrations of （Y3＋＋Nd3＋） and Al3＋（[Y3＋＋Nd3＋]=0.06 mol/L, [Al3＋]=0.1 mol/L）, aging time （6 d） and aging condition （in vessel）. The optimum microstructural characteristics of the high quality Nd：YAG nano-powders leading to transparent Nd：YAG ceramics including the pure YAG phase, the smallest crystallite size, a uniform crystallite size distribution, less density defects, uniform micro-components and the proper molar ratio of （Y3＋＋Nd3＋） and Al3＋（0.6148） were discussed.
