From: Magneto-optical borogermanate glasses and fibers containing Tb3+
Normalized Raman spectra for the BGB-xTb glasses in (a) low (~ 130–650 cm−1), (b) medium (~ 650–1050 cm−1), and (c) high (1050–1700 cm−1) frequency regions. Deconvolution of the Raman spectra for the 0, 4, 8, and 18 Tb glasses in the low (d–g), medium (h–k), and high (l–o) frequency regions.
