Bi 掺杂氧化物玻璃中的反应级数取决于玻璃主体的光学碱性。红色和近红外光致发光 (PL) 波段分别由 Bi2+ 和 Bi-n 簇产生。非常相似的中心存在于 Bi 和 Pb 掺杂氧化物和硫族化物玻璃中。双注入和 Bi 熔融掺杂硫属化物玻璃显示出新的 PL 谱带，表明新的 Bi 中心形成。在与观察到载流子类型反转的玻璃具有非常相似的成分的玻璃中观察到了 Bi 相关的 PL 带，表明这些现象与相同的 Bi 中心相关，我们认为它们是间隙 Bi2+ 和 Bi 簇。 (c) 2013 年美国光学学会
Reaction order in Bi-doped oxide glasses depends on the optical basicity of the glass host. Red and NIR photoluminescence (PL) bands result from Bi2+ and Bi-n clusters, respectively. Very similar centers are present in Bi- and Pb-doped oxide and chalcogenide glasses. Bi-implanted and Bi melt-doped chalcogenide glasses display new PL bands, indicating that new Bi centers are formed. Bi-related PL bands have been observed in glasses with very similar compositions to those in which carrier-type reversal has been observed, indicating that these phenomena are related to the same Bi centers, which we suggest are interstitial Bi2+ and Bi clusters.
