| 摘 要： | A series of novel Er^3＋/Yb^3＋ co-doped （85- x ） TeO2-15WO3-xB2O3 （TWB;x=2%,5%,8%（mole fraction） ） glasses were prepared. Influence of B203 on the spectroscopic properties of Er^3＋/Yb^3＋ co-doped tungsten-tellurite glasses were investigated. It is found that the intensity of 1.5μm fluorescence, lifetime of the ^4I13/2 level and upconversion fluorescence all decrease with the increase of B2O3 content. The product of full width at half maximum （FWHM） and stimulated emission cross-section （σe^peak） of Er^3＋ ：^4I13/2→^4I15/2 transition has an optimum when B203 is 5% （mole fraction）. The emission spectra of Er^3＋ ： ^4I13/2→^4I15/2 transition was analyzed using peak-fit routine, and an equivalent four-level system was proposed to estimate the stark splitting for the 411512 and ^4I13/2 levels of Er^3＋ ions in TWB glasses at room temperature. |

| Abstract: | A series of novel Er3 /Yb3 co-doped (85-x)TeO2-15WO3-xB2O3 (TWB; x=2%, 5%, 8% (mole fraction)) glasses were prepared. Influence of B2O3 on the spectroscopic properties of Er3 /Yb3 co-doped tungsten-tellurite glasses were investigated. It is found that the intensity of 1.5 μm fluorescence, lifetime of the 4I13/2 level and upconversion fluorescence all decrease with the increase of B2O3 content. The product of full width at half maximum (FWHM) and sti-mulated emission cross-section (σepeak) of Er3 ∶4I13/2→4I15/2 transition has an optimum when B2O3 is 5% (mole fraction). The emission spectra of Er3 : 4I13/2→4I15/2 transition was analyzed using peak-fit routine, and an equivalent four-level system was proposed to estimate the stark splitting for the 4I15/2 and 4I13/2 levels of Er3 ions in TWB glasses at room temperature. |
