Magneto-optical and fluorescence properties of Tb3+ doped glass-ceramics containing AlPO4
Source abstract
Abstract
In this paper, Tb 3+ doped AlPO 4 magneto-optical glass-ceramics were prepared by traditional melt quenching process and heat treatment techniques. The crystal structural, morphology, magneto-optical and fluorescence properties were systematically characterized via X-ray diffraction (XRD), projection Electron Microscope (STEM), Faraday rotation Angle test, photoluminescence spectra and fluorescence decay time. The transmittance curve shows that the visible light transmittance can reach 78% at least. Magneto-optical properties of Tb 3+ doped magneto-optical glass-ceramics were studied. When the incident wavelength is 633 nm, the 27B 2O 3-23GeO 2-20Al 2O 3-28Tb 2O 3-2P 2O 5 glass is heat-treated for 15h, the Verdet constant reaches -118.31 rad/(T•m), the transmission rate is 81%. In addition, the luminous intensity of the prepared glass-ceramics decreases with the growth of AlPO 4 crystallites. According to the CIE coordinate chart, all the coordinates are in the green range, and the chromaticity coordinates do not change significantly with the heat treatment time, indicating that the glass-ceramics prepared in this study have excellent luminescence stability.
