Abstract
A study of the chemiluminescence emission spectra of the peroxyoxalate chemiluminescence system has been undertaken, and the results show that fluorescer concentration has a significant impact on the shape and λ max of the spectra. As fluorescer concentration increases, the shape of the spectra changes and λ max shifts gradually to longer wavelength. For the 12 substituted bis(phenylethynyl)anthracences (BPEAs) studied, a 29–38 nm bathochromic shift was generally found. Variation of oxalate, hydrogen peroxide and sodium salicylate concentration had no observable influence on the shape and λ max of the spectra.
