中文摘要	bulk-lasses have been prepared in the teo2-zno-zncl2 systems. their characteristic temperatures were determined and analyzed. raman and ft-ir spectra were used to analyze the effect of zncl2 on the structure and spectral properties of tellurite glasses and oh- groups in this glass system. the spectroscopic properties including absorption spectra, emission cross-sections and fluorescence lifetimes of yb3+ in teo2-zno-zncl2 were measured and calculated. it is demonstrated that the progressive replacement less than 20 mol% of teo2 by zncl2 improves the thermal stability, removes the oh- groups, turns teo4 bipyramidal arrangement into teo3 (and/or teo3+1) trigonal pyramids structures and results in the decrease of the symmetry of the structure, which increases the emission cross-sections and lifetimes. but when the content of zncl2 up to 30 mol%, the glass system becomes more hygroscopic and introduces more oh- groups, which decrease the emission cross-sections and shorten the lifetimes. the results show that the glass system with (teo2)-te-69-(zno)-zn-10-20zncl(2)-1yb(2)o(3) is a desirable component for active laser media for high power generation.
