【摘要】 制备并研究了掺Er3+磷碲酸盐玻璃的热力学稳定性、吸收光谱、荧光光谱、Raman光谱和上转换发光性能。应用McCumber理论计算了Er3+离子从能级4I13/2到能级4I15／2跃迁的受激发射截面并分析了掺Er3+磷碲酸盐玻璃带宽特性和上转换发光性能。结果表明由于五氧化二磷的加入碲酸盐玻璃的各项性能参数都有所变化,掺Er3+磷碲酸盐玻璃具有较高的热稳定性、较好的带宽特性,同时上转换发光得到了较好的抑制,这说明其是一种优良的宽带平面光波导放大器的潜在的基质材料。更多还原

【Abstract】 Er3+ -doped phosphor-tellurite glass was fabricated and studied by the thermal stability, absorption spectrum, fluorescence spectrum, Raman spectrum and upconversion spectrum. The stimulated emission cross-section of 4I13/2→4I15/2 transitions were calculated by McCumber theory and bandwidth property and upconversion luminescence of Er3+ -doped phosphor-tellurite glass were analyzed. Result showed that optical and physical properties of tellurite glass were all changed as the addition of P2O5 and it has higher thermal stability, good bandwidth property, and upconversion luminescence was controlled efficiently. These results indicate that Er3+ -doped phosphor-tellurite glass can be used as a potential host material for planar optical waveguide amplifiers.更多还原
