摘要
In this paper, x at.% Nd3+: KGd0.1Lu0.9-x(WO4)2 (x = 1, 2, 3, 4, 5) crystals were grown by the top seed solution growth method (TSSG). The crystal structure was analyzed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR), and the crystal structure data was obtained by Rietveld refinement. The absorption spectra, near-infrared emission spectra and fluorescence decay curves of Nd3+ ions in the crystal were measured at indoor temperature. According to Judd-Ofelt theory, the spectral intensity parameters Ω2, Ω4 and Ω6 are calculated. When the doping concentration is 3 at.%, Ω2 is the largest, which is 3.84 × 10−20 cm2, while the spectral mass factor is the lowest, which is 0.3734. The absorption and emission cross-section are calculated by combining the absorption spectrum and emission spectrum, and the maximum calculated result of emission cross-section is 1.35 × 10−19 cm2. The results show that Nd3+: KGd0.1Lu0.9(WO4)2 crystals has great application potential in the 1.0 µm field.
