Abstract: 摘要 用熔融淬冷法制备了系列掺杂浓度的Dy3+:Ge-Ga-S-CsI硫卤玻璃样品，测试了样品拉曼光谱、折射率、吸收光谱、近红外及中红外荧光谱.应用Judd-Ofelt理论计算了Dy3+离子的强度参数 (Ωi, i=2,4,6)、自发辐射跃迁概率(A)、荧光分支比(β)、以及辐射寿命(τrad)等光谱参数.研究了810 nm激光抽运下样品中红 关键词: 硫系玻璃 / 中红外发光 / Dy3+掺杂 / 多声子弛豫 Abstract A series of chalcogenide glasses based on Ge-Ga-S-CsI system doped with different Dy3+ ions were synthesized by melt-quenching technique. The refractive indices, Raman spectra, absorption spectra, near- and mid-infrared fluorescence of glass samples were measured. The intensity parameters (Ωi, i=2,4,6), transition probabilities (A), branching ratios (β) and radiation lifetimes (τrad) have been predicted for Dy3+ ions in the samples by using the Judd-Ofelt theory. The mid-infrared fluorescence properties were investigated for different Dy3+ ion concentrations under 810 nm laser excitation. The multiphonon relaxation rates (Wmp) of Dy3+:6H13/2→6H15/2(2.86 μm) and6H11/2→6H13/2(4.38 μm), and the constant related to the e-p coupling strength (α) of Ge-Ga-S-CsI glasses were evaluated.
