One of the most challenging tasks in the field of light‐producing pyrotechnics is the generation of saturated blue light with high spectral purity. Only copper salts in combination with chlorine seem to be high‐performing blue light emitters. However, in modern pyrotechnics the application of chlorine should be avoided. Different strategies are presented to further fine‐tune literature‐known chlorine‐free blue‐light‐emitting pyrotechnical compositions. The copper iodate as well as the copper bromate systems have been studied by using small amounts of nitrogen‐rich compounds like 1,2,4‐triazole, 5‐amino‐1H‐tetrazole or 3‐nitro‐1H‐1,2,4‐triazole. To overcome sensitivity issues, a two‐component epoxy binder system was introduced. The application of both copper(I) iodide and copper(I) bromide in the same pyrotechnical formulation were considered as blue‐light‐emitting species. Further, a quite new approach by using copper(I) nitrogen‐rich coordination compounds was investigated to give a blue flame color. All relevant formulations were characterized with respect to their dominant wavelength and spectral purity as well as impact and friction sensitivity.

微调：无氯产生蓝光的烟火技术的进展

发光烟火领域最具挑战性的任务之一是产生具有高光谱纯度的饱和蓝光。只有与氯结合的铜盐似乎是高性能的蓝光发射器。然而，在现代烟火中，应避免使用氯。提出了不同的策略来进一步微调文献已知的无氯蓝光发射烟火组合物。碘酸铜和溴酸铜体系已通过使用少量富氮化合物如 1,2,4-三唑、5-氨基-1H-四唑或 3-硝基-1H-1,2,4 进行了研究-三唑。为了克服敏感性问题，引入了双组分环氧粘合剂系统。碘化铜（I）和溴化铜（I）在同一烟火配方中的应用被认为是发蓝光的物质。此外，研究了一种使用富铜（I）氮配位化合物的新方法，以产生蓝色火焰颜色。所有相关配方的特征在于它们的主波长和光谱纯度以及冲击和摩擦敏感性。
