摘　　要：采用传统高温熔融法在氮气、空气、氧气等不同气氛条件下制备了转变温度较低的40SnF2–30SnO–30P2O5（SSP）玻璃,系统地研究了不同气氛条件对其光谱性能和和结构的影响。结果表明：随着制备气氛氧含量的改变,SSP玻璃的紫外吸收边和激发光谱发生红移,其发光强度逐渐减低,部分Sn^2＋被氧化成Sn^4＋,玻璃中Sn^4＋含量逐渐增多,并且随着更多的氧进入玻璃参与成键,使得玻璃中Q^2基团中P—O键增多。40SnF2-30SnO-30P2O5 （SSP） glasses with a low glass transition temperature were prepared under different atmosphere conditions （i.e., nitrogen, air and oxygen） by a conventional high-temperature melting method. The photoluminescence properties of these glasses were investigated. As the preparation atmosphere changes from N2, air to O2, the UV absorption edge and photo luminescence excitation spectra of SSP glasses become red shifted, and the photo luminescence emission intensity gradually decreases. Based on the analysis by X-ray photoelectron spectroscopy and Raman spectroscopy, a part of Sn^2＋ in SSP glasses is oxidized to Sn^4＋ when the preparation atmosphere changes frona N2, air to O2, and the content of Sn^4＋ in the glasses gradually increases. Also, more oxygen enters the glass to participate in bonding, thus increasing the P-O bond in Q2 group.
