The preparation of transparent YAG ceramic composite structure and its optical properties
Abstract：The Study focus on the preparation method of the composite structure of YAG transparent ceramics. In yttrium oxide, alumina, Nd2O3 and Sm2O3 as raw materials, using solid state reaction method and tape casting synthesizedclad-core (Sm:YAG - Nd:YAG) transparent ceramic composite structure and multilayer composite structure of YAG/Nd:YAG/YAG transparent ceramics. Using microscope to observe the surface of ceramic grain growth, observe the ceramic surface and internal cracks, surface impurities and porosity using a scanning electron microscope, transmission spectra of ceramics by spectrophotometer. The results show that the finished product in the presence of some pores and impurity, it also exists absorption peaks in the visible spectral range, the process needs to be further improved, but consistent with the overall goal of the project.
