Studies of the Spectroscopic Properties of Lead-Gallium Oxyfluoride (LGOF) Glasses and Glass-Ceramics Activated by Er3+ and Er3+/Yb3+ Ions

摘要

Lead-gallium glasses, due to the absence of typical glass-forming components, are characterized by an increased tendency to crystallization. Despite this, they are interesting materials due to a shift of IR absorption edge up to 6 - 7 μm. Spectroscopic properties of Er and Er-Yb doped lead-gallium glasses are investigated at low and room temperature in the near infrared region between 800 and 1800 nm. Received results are discussed base on transitions originating from the crystal filed splitting ^{4I15/2 and 4I13/2 levels.}
