Synthesis of submicron-sized spherical Y2O3 powder for transparent YAG ceramics

▶ Spherical monodispersed, submicron-sized Y2O3 powder was prepared via a homogeneous precipitation method. ▶ Highly transparent YAG ceramics was fabricated using the spherical Y2O3 powder and a commercial Al2O3 powder. ▶ The in-line transmittances of the as-fabricated YAG ceramics at the wavelength of 1064 nm and 400 nm were 82.8% and 79.5%, respectively.
