摘要：

Nd:GGG ultrafine polycrystalline powders for transparent ceramics precursor powder were synthesized by sol-gel method, and sol-gel transformation mechanics was discussed. Nd : GGG polycrystalline material was analyzed by XRD, SEM and fluorescence spectrum. XRD analysis shows that Nd: GGG polycrystalline phase is formed at 1000 degrees C, and the grain size increases with rising sintering temperature by SEM, and the particle size is about 100 nm. They are used as transparent ceramics precursor powder. Fluorescence spectrum test shows that the strongest fluorescence emission peak is 1061.45 nm for the Nd:GGG polycrystalline precursor powder, which is the fluorescence-emission of Nd3+4F3/2-I-4(11/2).
