首次将具有较高声子能量的WO3氧化物引入到由TeO2单键Bi2O3单键TiO2组成的Er3+/Yb3+/Ce3+三掺杂亚碲酸盐基玻璃中，以提高1.53μm波段荧光发射。测量了 X 射线衍射 (XRD) 曲线、拉曼光谱、吸收光谱和 1.53 μm 波段荧光光谱，并计算了 Judd-Ofelt 强度参数、受激发射和吸收截面以及辐射量子效率，以评估 WO3 量对玻璃结构和光谱性能（尤其是 1.53 μm 波段）的影响。 荧光。结果表明，引入适量的WO3氧化物可以通过增强Er3+/Ce3+离子之间的声子辅助能量转移来进一步提高1.53μm波段荧光强度，并且通过计算能量转移微参数和声子贡献比来详细定量研究Er3+/Yb3+(Er3+/Ce3+)离子之间的能量转移机制。结果表明，所制备的含有适量WO3氧化物的Er3+/Yb3+/Ce3+三掺杂亚碲酸盐玻璃是一种适用于1.53 μm宽带高增益EDFA的潜在增益介质。
For the first time, the WO3oxide with relatively high phonon energy was introduced into the Er3+/Yb3+/Ce3+tri-doped tellurite-based glasses with composition of TeO2single bondBi2O3single bondTiO2to improve the 1.53 μm band fluorescence emission. The X-ray diffraction (XRD) curves, Raman spectra, absorption spectra and 1.53 μm band fluorescence spectra were measured, along with the Judd–Ofelt intensity parameters, stimulated emission and absorption cross-sections, and radiative quantum efficiencies were calculated to evaluate the effects of WO3amount on the glass structure and spectroscopic properties especially the 1.53 μm band fluorescence. It is shown that the introduction of an appropriate amount of WO3oxide can further improve the 1.53 μm band fluorescence intensity through an enhanced phonon-assisted energy transfer between Er3+/Ce3+ions and the energy transfer mechanisms between Er3+/Yb3+(Er3+/Ce3+) ions are investigated quantitatively in detail by calculating energy transfer microparameters and phonon contribution ratios. The results indicate that the prepared Er3+/Yb3+/Ce3+tri-doped tellurite glass with an appropriate amount of WO3oxide is a potential gain medium applied for the 1.53 μm band broad and high-gain EDFA.
