Rare earth – doped inorganic glasses have attracted much attention to develop broadband
optical amplifiers operating within near-infrared (NIR) low-loss wavelength region. In
particular, the near-infrared luminescence corresponding to

transition of Er
3+
has
been often used in optical telecommunication for signal amplification. However, the commercial
Er
3+
doped fiber amplifiers (EDFA) based on silica glass exhibit a relatively narrow linewidth
that limits broadband NIR transmission [1]. For that reason, it is necessary to search for a new
glass host matrices with rare earths exhibiting relatively broader emission lines and longer
lifetimes for signal amplification in optical telecommunication. Among the rare earth ions,
trivalent Pr
3+
exhibits broadband near-infrared luminescence covering a wavelength range from
1.2 μm to 1.7 μm, which is important for optical fiber amplifiers operating at O-, E-, S-, C-, and
L-band [2].
In this work, spectroscopic properties of rare earth ions in barium gallo-germanate glasses
have been examined. Our previously published works were demonstrated that barium gallo-
germanate glass-host containing Er
3+
[3] and Pr
3+
[4] is promising for broadband near-infrared
luminescence. The intention of our work was to prepare thermally stable Ln
3+
-doped barium
gallo-germanate glasses (where Ln = Nd, Pr, Er, Ho) and to characterize their near-infrared
luminescence properties.
Keywords: germanate glasses; rare earth ions; luminescence; spectroscopic properties
