The generation of a high quality blue pyrotechnic flame has been a challenge since decades. According to some researches, the main problem in pyrotechnics is the lack of high temperature emitters, and the situation becomes even more difficult when it deals with the emitters of blue flames. To produce blue flame colors, mostly copper and chlorine containing compounds are used to generate the blue light emitting species CuCl. However, chlorinated organic products, which are formed during the combustion process, are believed to be quite toxic. Therefore, Copper(I) bromide was investigated as an alternative emitter for blue flame pyrotechnic compositions.
