摘要

The influence of Er3+ ions on the spectra of Yb3+,Er3+∶ Sc2SiO5 (SSO) single crystal,which was obtained by Czochralski (Cz) method,is discussed.The absorption coefficient at 980 nm was 13.36 cm-1 with a peak absorption cross-section of 1.46 × 10-20 cm2.The emission cross-sections at 1034 nm and 1062 nm were 5.5 × 10-21 cm2 and 4.9 × 10 21 cm2,respectively.The fluorescence lifetime was estimated as 1.24 ms at 1061 nm.The mechanical properties of SSO single crystal were also presented.
