采用熔融淬火技术制备了初始成分为teo2 - geo2 - li2o - nb2o5的Er3+/Ce3+共掺杂和b2o3改性碲酸盐玻璃，在Er3+掺杂光纤放大器（edfa）和激光器中具有潜在的应用前景。通过测量玻璃样品的吸收光谱、荧光光谱、上转换光谱、拉曼光谱和差示扫描量热仪（DSC）曲线，评价b2o3改性对Er3+ 1.53 μm波段光谱特性、玻璃主体结构性质和热稳定性的影响。结果表明，在980 nm激发下，引入适量的b2o3氧化物可以通过增强Er3+到Ce3+离子的声子辅助能量转移（ET）进一步提高1.53 μm波段的荧光发射，并通过计算微观参数和声子贡献比进行了定量研究，以阐明ET的机理。同时，b2o3的加入使玻璃基体的热稳定性略有提高。基于稀土离子速率和光功率传播方程，模拟了1.53 μm波段的光信号放大。在含6 mol% b2o3的Er3+/Ce3+共掺碲酸盐玻璃纤维中，在1532 nm处信号增益增加了约1.4 dB，在功率为200 mW、泵浦波长为980 nm、波长为50 cm的光纤中，信号增益最大可达31 dB。结果表明，制备的Er3+/Ce3+共掺碲酸盐玻璃经适量b2o3修饰后，作为增益介质应用于1.53 μm波段edfa和激光器具有良好的前景。
Er3+/Ce3+co-doped and B2O3modified tellurite glasses with initial composition of TeO2–GeO2–Li2O–Nb2O5were prepared using melt-quenching technique for potential applications in Er3+-doped fiber amplifiers (EDFAs) and lasers. The absorption spectra, fluorescence spectra, up-conversion spectra, Raman spectra and differential scanning calorimeter (DSC) curves of glass samples were measured to evaluate the effect of B2O3modification on the 1.53 μm band spectroscopic properties of Er3+, structural nature and thermal stability of glass hosts. It was shown that the introduction of an appropriate amount of B2O3oxide can further improve the 1.53 μm band fluorescence emission through an enhanced phonon-assisted energy transfer (ET) from Er3+to Ce3+ions under the excitation of 980 nm, and the quantitative studies were carried out to elucidate the ET mechanism via calculating the microscopic parameters and phonon contribution ratios. Meanwhile, the thermal stability of glass hosts increases slightly with the introduction of B2O3oxide. Furthermore, the 1.53 μm band optical signal amplification was simulated based on the rare-earth ion rate and light power propagation equations. An increment in signal gain by about 1.4 dB at 1532 nm was observed in the Er3+/Ce3+co-doped tellurite glass fiber containing 6 mol% amount of B2O3oxide, and the maximum signal gain reaches to 31 dB on a 50 cm fiber pumped at 980 nm with power 200 mW. The present results indicate that the prepared Er3+/Ce3+co-doped tellurite glass modified by an appropriate amount of B2O3oxide has good prospect as a gain medium applied for 1.53 μm band EDFAs and lasers.
