Influence of the melting atmosphere on Yb3+/Al3+ co-doped silica glass with powder melting technology

We demonstrated the formation of Yb2+ ions in Yb3+/Al3+ co-doped silica glass using the powder melting technology based on the high-frequency plasma furnace. The Yb3+ ions can be deoxidated into Yb2+ ions under the atmosphere of N2 or Ar. The appearance and optical properties of the Yb3+/Al3+ co-doped silica glass are also changed.
