摘　　要：采用传统的熔融法制备了Er^(3+)掺杂的新型铋酸盐玻璃(Li_(2)O‑SrO‑ZnO‑Bi_(2)O_(3),LSZB),并对其光谱性质进行了表征,分析了玻璃的拉曼光谱、吸收光谱、荧光光谱,利用Judd‑Ofelt理论研究了其荧光特性。LSZB玻璃样品中Er^(3+)的4I_(13/2)→4I_(15/2)跃迁发射峰位于1.53μm处,半高宽约为78 nm。样品中Er^(3+)的4I_(13/2)能级寿命为2.848 ms,量子效率为99.93%,受激发射截面达到9.76×10^(-21)cm^(2)。以上结果显示,Er^(3+)掺杂LSZB玻璃有良好的光谱特性。Er^(3+)‑doped novel bismuthate(Li_(2)O‑SrO‑ZnO‑Bi_(2)O_(3),LSZB)glasses have been fabricated through the conventional melt‑quenching method,and the spectroscopic properties of Er^(3+)in the glasses were characterized.The density,refractive indexes,Raman spectra,optical absorption spectra,fluorescence spectra and radiative lifetime of the glasses were measured and analyzed.The fluorescence properties were calculated by using the Judd‑Ofelt theory.The emission peak from the Er^(3+):4I_(13/2)→4I_(15/2)transition located around 1.53μm with a full width at half maximum(FWHM)of~78 nm.The lifetime of the 4I_(13/2)level was 2.848 ms and the quantum efficiency was 99.93%,respectively.The emission cross section was estimated to be 9.76×10^(-21)cm^(2).In summary,the above results indicate that Er^(3+)‑doped LSZB glasses have good spectral characteristics.
