Synthesis of Nd:GGG Powder by Liquid Phase Co-Precipitation or Solid State Method and Preparation of its Transparent Ceramic

Abstract

Neodymium-doped gadolinium gallium garnet (Nd:GGG) precursor and ceramic were prepared by liquid phase co-precipitation or solid-state methods, and the properties were studied. The results indicate that the precursor prepared with the liquid phase co-precipitation method has a small particle size. The sub-transparent ceramic was obtained after the body sintered for 2-3h at 1650°C at 1100Pa using liquid-phase co-precipitation method. When the body was sintered at 1750°C for 2-3h, a sintered body with non-transparency was obtained. The absorption spectrum and fluorescence spectrum of the sub-transparent ceramic were measured with the cross section at 807nm was calculated as1×10-20cm2 and the strongest emission peak located at 1061nm.
