Yb doped MgO transparent ceramics generated through the SPS method

Yb doped (0, 0.02, 0.1 and 0.5 at%) MgO transparent ceramics were synthesized through spark plasma sintering (SPS) at the relatively low temperature of 1100 °C for 5–60 min under a pressure 105 MPa. The effects dopant concentration holding time on densification microstructure evolution investigated. All reached relative density greater than 99.20%. 0.02% Yb-doped ceramic sintered 60 showed highest in-line transmittance, 80% 1030 nm, value close to that single crystals. improved degree control grain growth. Herein, influence doping crystalline phase was explored, photoluminescence properties in
