Wavelength dependence of Tb 3+ doped magneto-optical glass Verdet constant

Magneto-optical glass is a category of optical materials. In this study, a series of Tb3+ doped Ga2O3–B2O3–SiO2–GeO2 (GBSG) glasses were prepared and studied. Through the density test, it was found that the structure of the magneto-optical glass tended to be dense. At the same time, the result of infrared spectrum shows that some changes happened to the structure of the sample with different Tb3 + concentration, resulting in the change of the...
