摘要:
Special pure 1300 ppmw Pr(3 + )-doped Ga3Ge31As18Se48 glass is prepared; its microstructure, impurity content, thermal, crystallization, optical and photo-luminescent properties are investigated. The glass microstructure, according to Raman scattering spectroscopy data, consists mainly of Ge(Se-1/2)(4), As4Se3 and (Se-3/2)Ge-Ge(Se-3/2) structural units. The glass has a low content of residual impurities, a wide transmission range (0.9-16 mu m), a high glass transition temperature (356 degrees C), and a low tendency to crystallization. When pumping laser radiation at a wavelength of 1.56 mu m the studied glass shows intense photoluminescence in the spectral regions 2.1-3.2 mu m and 3.5-6 mu m. The measured emission lifetime at 4.5-5 mu m wavelengths was 12.5 ms. The obtained Pr(3 + )-doped chalcogenide glass is promising for fabrication of active mid-IR optical fibers.
