Abstract

Broadband NIR photoluminescence (from 1000 to 2500 nm) was observed from partially reduced AlCl₃/ZnCl₂/BiCl₃ glass, containing subvalent bismuth species. The luminescence consists of three bands, assigned to Bi⁺ , Bi₂⁴⁺, and Bi₅³⁺ ions. The physical and optical characteristics of these centers and possible contribution to NIR luminescence from bismuth-doped oxide glasses are discussed.

摘要

在含有低价铋物种的部分还原的AlCl₃/ZnCl₂/BiCl₃玻璃中观察到了宽带近红外光致发光（波长范围为1000至2500 nm）。该发光由三个谱带组成，分别归属于Bi⁺、Bi₂⁴⁺和Bi₅³⁺离子。讨论了这些中心的物理和光学特性以及铋掺杂氧化物玻璃对近红外发光可能的贡献。
