实验发现：铜离子Ｃｕ２＋明显增强了Ｌｕｍｉｎｏｌ－ＮａＯＨ和Ｌｕｍｉｎｏｌ－Ｃａ（ＯＨ）２两种水溶液的声致荧光强度，并使它们的最大声致荧光峰分别发生了６ｎｍ和９ｎｍ的红移现象．但这种离子对Ｌｕｍｉｎｏｌ－Ｎａ２ＣＯ３水溶液的影响与上述相反，并对应发生了５ｎｍ的篮移现象．然而，Ｃｕ２＋对这３种溶液的声致荧光的发射波长均不构成严重影响．
It was found that the copper (II) -containing Cu2 + enhanced the acoustically-induced fluorescence intensity of both Luminol-NaOH and Luminol-Ca (OH) 2 aqueous solutions and caused their redox shifts of 6nm and 9nm respectively. However, the effect of this ion on the Luminol-Na2CO3 aqueous solution is opposite to that described above, and a corresponding shift of 5 nm occurs. However, Cu2 + did not have a serious impact on the acoustic emission wavelengths of the three solutions.
