Reaction order in Bi-doped oxide glasses depends on the optical basicity of the glass host. Red and NIR photoluminescence (PL) bands result from Bi(2+) and Bin 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 Bi(2+) and Bi clusters.
铋掺杂氧化物玻璃中的反应级数取决于玻璃基质的光学碱度。红色和近红外光致发光（PL）带分别由Bi(2+)和Bi团簇产生。铋和铅掺杂的氧化物及硫属化物玻璃中存在非常相似的中心。铋离子注入和铋熔体掺杂的硫属化物玻璃呈现出新的PL带，表明形成了新的铋中心。在与观察到载流子类型反转的玻璃成分非常相似的玻璃中观察到了与铋相关的PL带，这表明这些现象与相同的铋中心有关，我们认为这些中心是间隙Bi(2+)和铋团簇。
