Abstract
MgAl2O4 transparent phosphor ceramics were fabricated by hot-pressing and hot isostatic pressing using high-purity ultrafine MgAl2O4 powder mixed with phosphor. The microstructures of transparent phosphor ceramics were characterized by SEM and EDS. Moreover, the hardness and bending strength of transparent ceramics were measured. Effect of phosphor concentration (0~20%) on microstructure, hardness and bending flexture of transparent ceramics was analyzed. It was found that phosphor doping plays an important role in improving the mechanical property of transparent ceramics. So applying this kind of transparent phosphor ceramic to LED components as packaging material can significantly improve the lifetime and reliability of LED products.
