摘要: 在研制的Er3+/Ce3+共掺低声子能量碲酸盐玻璃(TeO2-Bi2O3-TiO2)中, 分别引入高声子能量WO3、SiO2和B2O3氧化物组分, 测试了玻璃样品400~1700 nm范围内的吸收光谱、1.53 μm波段荧光谱、Er3+离子荧光寿命和拉曼光谱, 结合McCumber理论计算了Er3+离子光谱参数. 结果表明: 高声子能量氧化物组分的引入, 能使声子参与的Er3+/Ce3+离子间能量传递过程变得更为有效, 增加了Er3+离子亚稳态能级4I13/2上粒子数积累, 从而增强1.53 μm波段荧光发射. 另外, 高声子能量氧化物组分的引入还可以增加荧光半高宽(FWHM)和带宽品质因子(σe×FWHM). 研究结果对于获取具有优异光谱特性的掺Er3+光纤放大器(EDFA)的玻璃基质具有实际意义.

Abstract: High phonon energy oxides of WO3, SiO2 and B2O3 were introduced into the Er3+/Ce3+ co-doped tellurite glass (TeO2-Bi2O3-TiO2) with low phonon energy, respectively. The absorption spectra in the wavelength region of 400–1700 nm, fluorescence spectra of 1.53 μm band, fluorescence lifetimes of Er3+ and Raman spectra of the glasses were measured. The spectral parameters of Er3+ were calculated with the help of McCumber theory. It is shown that the energy transfer process between Er3+ and Ce3+ becomes more effectively when introducing the high phonon energy oxide, and the 1.53 μm band fluorescence emission corresponding to Er3+:4I13/24I15/2 transition enhances accordingly due to the increased population of Er3+ in the 4I13/2 level. Meanwhile, the fluorescence width at half magnitude (FWHM) and bandwidth quality factor (σe×FWHM) can be improved with the introducing of high phonon energy oxide. The results provide practical significance to obtain the excellent spectroscopic glass host applied for the Er3+-doped fiber amplifier (EDFA).
