测量了熔融在Ar中的硅酸盐、硼酸盐和磷酸盐玻璃中Ce3+离子的荧光光谱。在20Li(2)O-20RO-60SiO(2)玻璃样品中，Ce3+在紫外区的相对荧光强度随BaO含量的降低而增加，而在20Li(2)O-20RO-60SiO(2)玻璃样品中，Ce~(3+)在紫外区的相对荧光强度依次为R=Ba、Ca、Sr和Mg。而在磷酸盐玻璃样品中，Ce3+的相对荧光强度不随玻璃成分的变化而变化。根据Ce3+-Ce4+在氧化物玻璃中的氧化还原反应，讨论了Ce3+相对荧光强度与组成的关系。(C)2004爱思唯尔B.V.保留所有权利。
Fluorescence spectra of Ce3+ ions in silicate, borate, and phosphate glasses melted in Ar were measured. The relative fluorescence intensity of Ce3+ in the ultraviolet region increased in the order of R = Ba, Ca, Sr, and Mg in the 20Li(2)O-20RO-60SiO(2) glass samples and with decreasing BaO content in the BaO-B2O3 glass samples, respectively. In contrast, the relative fluorescence intensity of Ce3+ did not change with varying the glass composition in phosphate glass samples. The compositional dependence of the relative fluorescence intensity of Ce3+ is discussed in terms of redox reaction of Ce3+-Ce4+ in oxide glasses. (C) 2004 Elsevier B.V. All rights reserved.
