Summary: | •To study the effect of changing Ho3+ ion doping concentration in 32GeO2–20B2O3–5P2O5–3ZnO-40Tb2O3 glass on the structure, physical properties and magneto-optical properties of magneto-optical glass.•The wavelength and temperature dependence of Verdet constant of magneto-optical glass GBPZ-T40-xHo (x = 0, 2, 4, 6, 8 and 10 mol%) was studied.•When the incident wavelength is 633 nm, GBPZ-T40-xHo (x = 0, 2, 4, 6, 8 and 10 mol%) has a large Verdet constant, higher than the commercialized terbium gallium garnet (TGG) crystal, it has a wide range of applications and research value.
In this paper, 32GeO2–20B2O3–5P2O5–3ZnO-40Tb2O3-xHo2O3 (x = 0, 2, 4, 6, 8 and 10 mol%) Faraday glasses doped with different concentrations of Ho3+ ions are prepared. The structure and physical properties of the 32GeO2–20B2O3–5P2O5–3ZnO-40Tb2O3-xHo2O3 (x = 0, 2, 4, 6, 8 and 10 mol%) Faraday glass system are investigated by XRD, FT-IR and theoretical calculations. The effect of the different concentrations of Ho3+ ions, incident wavelengths and test temperatures on the Verdet constants are studied. It was found that the magneto-optical properties of 32GeO2–20B2O3–5P2O5–3ZnO-40Tb2O3-xHo2O3 (x = 0, 2, 4, 6, 8 and 10 mol%) Faraday glass has a certain dependence on the changes of incident wavelength and the test temperature. At room temperature, with the increase of Ho3+ ion doping concentrations, the values of Verdet constants increase continuously at 633 nm. 32GeO2–20B2O3–5P2O5–3ZnO-40Tb2O3–10Ho2O3 Faraday glass has the highest Verdet constant value (-172.65 rad/(T·m)), which is increased by -42.35 rad/(T·m) compared with 32GeO2–20B2O3–5P2O5–3ZnO-40Tb2O3–10Ho2O3 Faraday glass without Ho3+ ions (-130.30 rad/(T·m)). And it is much higher than that of the commercialized terbium gallium garnet crystal (-134 rad/(T·m)), indicating that the incorporation of Ho3+ ions with a large magnetic moment can significantly improve the properties of the magneto-optical glass, which has not been reported in other literatures. At the same time, it is found that the Verdet constant of 32GeO2–20B2O3–5P2O5–3ZnO-40Tb2O3–10Ho2O3 Faraday glass decreased with the increase of test temperature. These findings have important implications for the application of magneto-optical glass in the fields of optical fiber, laser, information, and magneto-optical devices.
